Description

2-Alkyliden- und 2-(Alkyl-1-en)-cyclopentanone als Riechstoffe 2-Alkylidene and 2- (alkyl-1-ene) cyclopentanones as fragrances
Die Erfindung betrifft neue 2-Alkyliden- und 2-(Alkyl-1-en)-cyclopentanone, ihre Verwendung als Riechstoffe sowie parfümierte Produkte und Riechstoffmischungen enthaltend die erfindungsgemäßen Verbindungen, sowie ein Verfahren zu ihrer Herstellung.The invention relates to novel 2-alkylidene and 2- (alkyl-1-ene) cyclopentanones, their use as fragrances and perfumed products and fragrance mixtures containing the compounds of the invention, and to a process for their preparation.
In der Riechstoffindustrie besteht ein nachhaltiges Interesse an der Entwicklung von neuen Riechstoffen, um somit die Kreation von neuen Parfümölen für die alkoholische, wie auch funktionelle Parfümerie zu ermöglichen. Verbindungen mit blumigen Geruch sind hierbei unverzichtbare Komponenten in der Duftstoff¬ industrie. Eine besondere Klasse dieser blumigen Riechstoffe sind Verbindungen mit blumig-jasminartigen Noten. Strukturell zeichnen sich Verbindungen mit blumig-jasminartigen Noten in manchen Fällen durch einen Cyclopentanon-Ring aus, der in α-Position durch einen Alkyl- oder Alkylen-Rest und in ß-Position durch einen Methylacetat Rest substituiert ist. Die zwei wichtigsten Vertreter dieser Klasse von Riechstoffen sind die natürlich vorkommenden 3-Oxo-2-pentyl- cyclopentyl-essigsäuremethylester (II) (Methyldihydrojasmonat, Hedione®, Firmenich S.A.) und 3-Oxo-2-(pent-2-enyl)-cyclopentyl-essigsäuremethylester (IM) (Methyljasmonate). Ein weiterer Vertreter dieser Substanzklasse ist 3-Oxo-2- pentyl-cyclopent-1-enyl-essigsäuremethylester (IV), diese Verbindung wird aber weniger als Riechstoff, sondern vielmehr als Vorprodukt für die Synthese von 3- Oxo^-pentyl-cyclopentyl-essigsäuremethylester (II) eingesetzt.In the fragrance industry, there is a sustained interest in the development of new fragrances, thus enabling the creation of new perfume oils for both alcoholic and functional perfumery. Compounds with a floral odor are indispensable components in the perfume industry. A special class of these flowery fragrances are compounds with floral-jasmine-like notes. Structurally, compounds with flowery-jasmine-like notes are sometimes characterized by a cyclopentanone ring which is substituted in the α-position by an alkyl or alkylene radical and in the β-position by a methylacetate radical. The two most important members of this class of scents are the naturally occurring 3-oxo-2-pentyl cyclopentyl-methyl acetate (II) (methyldihydrojasmonate, Hedione ®, Firmenich SA) and 3-oxo-2- (pent-2-enyl) -cyclopentyl-acetic acid methyl ester (IM) (methyl jasmonate). Another representative of this class of substances is 3-oxo-2-pentyl-cyclopent-1-enyl-acetic acid methyl ester (IV), but this compound is less as a fragrance, but rather as a precursor for the synthesis of 3-oxo ^ -pentyl-cyclopentyl- Acetic acid methyl ester (II) used.
Methyldihydrojasmonat (II) zeichnet sich durch eine warme, blumige Jasminnote, gepaart mit der frischen blumigen Weichheit einer Zitrone aus. Methyljasmonat (IM), welches ein flüchtiger Bestandteil des Jasminöls ist, besitzt einen starken blumig-krautigen, süßen Geruch, der an Jasmin absolute erinnert. Demgegenüber steht ein schwacher fruchtiger Geruch, der nicht an Jasmin erinnert, für die Cyclopentylverbindung (IV).Methyldihydrojasmonat (II) is characterized by a warm, floral Jasminnote, coupled with the fresh floral softness of a lemon. Methyl jasmonate (IM), which is a volatile component of jasmine oil, has a strong flowery-herbaceous, sweet odor reminiscent of jasmine absolute. On the other hand, a weak fruity odor reminiscent of jasmine is found for the cyclopentyl compound (IV).
Aus S. Shicheng et al., Youji Huaxue, 1986, 20, 453 ist [2-Pentyliden-3-oxo- cyclopentyl]-essigsäuremethylester bekannt, welcher als Zwischenprodukt erhalten wird, und für die weitere Synthese zu Methyldihydrojasmonat der obigen Formel Il und Methyldihydroneojasmonat benutzt wird.S. Shicheng et al., Youji Huaxue, 1986, 20, 453 discloses [2-pentylidene-3-oxo-cyclopentyl] -acetic acid methyl ester, which is obtained as an intermediate, and for the further synthesis to methyl dihydrojasmonate of the above formula II and II Methyldihydroneojasmonat is used.
In WO 2004/043895 wird ein Prozess zur Synthese von Alkylidencyclopentanon- Derivaten (V) beschrieben.In WO 2004/043895 a process for the synthesis of Alkylidencyclopentanon- derivatives (V) is described.
Hierbei repräsentiert G eine C=O oder C(OR)2 Gruppe, R1 z. B. n-Butyl als reine Alkylgruppe ohne Heteroatome und R2 eine unverzweigte oder verzweigte Ci bis C4 Alkylgruppe. Es wird ausgeführt, dass die Verbindungen der Formel (V) als Zwischenprodukte für die Synthese der oben beschriebenen Verbindungen (Il - IV) eingesetzt werden können. Here G represents a C = O or C (OR) 2 group, R 1 z. B. n-butyl as a pure alkyl group without heteroatoms and R 2 is an unbranched or branched Ci to C 4 alkyl group. It is stated that the compounds of the formula (V) can be used as intermediates for the synthesis of the compounds (II-IV) described above.
Die Auswahl an blumig-jasminigen Riechstoffen, die dem Parfümeur für die Kreation von Parfümölen zur Verfügung stehen, ist sehr begrenzt.The range of floral-jasmine fragrances available to the perfumer for the creation of perfume oils is very limited.
Es war deshalb die Aufgabe der vorliegenden Erfindung, Jasmin-Riechstoffe anzugeben, deren Geruchsprofil sich von dem der oben beschriebenen Verbindungen (Il - IV) unterscheidet. Vorteilhafterweise sollten dabei die anzugebenden Jasmin-Riechstoffe originelle geruchliche Aspekte aufweisen, um so die für die Komposition von Parfüms zur Verfügung stehende Rohstoffpalette zu erweitern.It was therefore the object of the present invention to provide jasmine fragrances whose odor profile differs from that of the above-described compounds (II-IV). Advantageously, the jasmine fragrances to be indicated should have original odor aspects in order to expand the range of raw materials available for the composition of perfumes.
Erfindungsgemäß wird diese Aufgabe gelöst durch die Verwendung einer Verbindung der Formel (Ia) oder (Ib):According to the invention, this object is achieved by the use of a compound of the formula (Ia) or (Ib):
wobei in jeder der Formeln (Ia) und (Ib)wherein in each of the formulas (Ia) and (Ib)
R1 H oder Methyl undR 1 is H or methyl and
R eine verzweigte oder unverzweigte d- bis C5-Alkylgruppe ist,R is a branched or unbranched C 1 to C 5 alkyl group,
als (Jasmin-)Riechstoff. - A -as (jasmine) fragrance. - A -
In den Formeln (Ia) und (Ib) kennzeichnen geschlängelte Linien jeweils das E- Isomer, das Z-Isomer und die E/Z-Isomerenmischungen.In the formulas (Ia) and (Ib), meandering lines indicate the E isomer, the Z isomer and the E / Z isomer mixtures, respectively.
Als verzweigte oder unverzweigte d- bis C5-Alkylgruppe kann insbesondere eingesetzt werden: Methyl, Ethyl, n-Propyl, /so-Propyl, n-Butyl, se/c.-Butyl, iso- Butyl, n-Pentyl, /so-Pentyl und 3-Methylbutyl. Bevorzugt sind insoweit jedoch die Alkylreste Ethyl, n-Propyl, /so-Propyl, n-Butyl, sek.-Butyl, iso-Butyl und n-Pentyl und besonders bevorzugt die Alkylreste Ethyl, n-Propyl, n-Butyl und n-Pentyl.As branched or unbranched C 1 to C 5 alkyl group it is possible in particular to use: methyl, ethyl, n-propyl, / so-propyl, n-butyl, sec-butyl, isobutyl, n-pentyl, and the like Pentyl and 3-methylbutyl. However, the alkyl radicals ethyl, n-propyl, / so-propyl, n-butyl, sec-butyl, isobutyl and n-pentyl and particularly preferably the alkyl radicals ethyl, n-propyl, n-butyl and n-butyl are preferred. pentyl.
Ein weiterer Gegenstand der Erfindung sind Verbindungen der Formel (Ia) und (Ib), wobeiAnother object of the invention are compounds of formula (Ia) and (Ib), wherein
R1 H oder Methyl ist undR 1 is H or methyl and
R2 eine verzweigte oder unverzweigte Ci bis C5 Alkylgruppe ist, wobeiR 2 is a branched or unbranched C 1 to C 5 alkyl group, wherein
die bereits aus WO 2004/043895 bekannte Verbindung der Formel (Ia) mit R1 = H und R2 = n-Propyl ausgenommen ist.the already known from WO 2004/043895 compound of formula (Ia) with R 1 = H and R 2 = n-propyl is excluded.
Die erfindungsgemäß zu verwendenden Verbindungen der Formel (Ia) und (Ib) können in Form eines reinen optisch aktiven Enantiomers, einer optisch aktiven Mischung verschiedener Enantiomere oder einer sonstigen beliebigen Mischung der von der Formel I umfassten Stereoisomere vorliegen.The compounds of the formula (Ia) and (Ib) to be used according to the invention can be present in the form of a pure optically active enantiomer, an optically active mixture of different enantiomers or any other mixture of the stereoisomers encompassed by the formula I.
Die erfindungsgemäß zu verwendenden Verbindungen der Formel (Ia) und (Ib) besitzen parfümistisch interessante jasminartige Geruchsnoten und zeichnen sich überdies durch die gewünschten interessanten Beinoten aus. Überraschenderweise besitzen die Verbindungen der Formel (Ia) und (Ib) neben der intensiven Jasminnote sehr schöne fruchtige und lactonige Aspekte. Dies ist überraschend, denn der Geruch der Verbindung (IV), welche eine endocyclische α,ß-ungesättigte Doppelbindung enthält, erinnert nur entfernt an Jasmin, wohingegen die Verbindungen der Formel (Ia) mit einer exocyclischen α,ß- ungesättigten Doppelbindung wie beschrieben einen sehr intensiven Jasmingeruch aufweisen.The compounds of the formula (Ia) and (Ib) which are to be used according to the invention have perfumistically interesting jasmine-like odor notes and, moreover, are distinguished by the desired interesting legotenes. Surprisingly, the compounds of the formula (Ia) and (Ib) in addition to the intense Jasminnote have very beautiful fruity and lactone aspects. This is surprising since the odor of the compound (IV) which contains an endocyclic α, β-unsaturated double bond is only remotely reminiscent of jasmine, whereas the compounds of the formula (Ia) have an exocyclic α, β- unsaturated double bond as described have a very intense Jasmingeruch.
Sensorisch besonders wertvoll sind erfindungsgemäß zu verwendende Verbindungen der Formeln (Ia) und (Ib), wobei R1 = H ist und R2 vorzugsweise Ethyl, n-Propyl, n-Butyl oder n-Pentyl ist, besonders bevorzugt ist R1 = H und R2 = n-Propyl und n-Butyl.Of particular sensory value according to the invention are compounds of the formulas (Ia) and (Ib) to be used, where R 1 = H and R 2 is preferably ethyl, n-propyl, n-butyl or n-pentyl, R 1 = H being particularly preferred and R 2 = n-propyl and n-butyl.
Die Verbindungen der Formel (Ia) besitzen einen starken strahlenden Jasmin- Geruch mit fruchtigen und citrischen Aspekten, und die Verbindungen der Formel (Ib) besitzen einen weicheren, nichts so strahlenden Jasmin-Geruch, mit lactonigen Aspekten.The compounds of formula (Ia) have a strong radiant jasmine odor with fruity and citrus aspects, and the compounds of formula (Ib) have a softer, less radiant jasmine odor, with lactone aspects.
Gemäß einem weiteren Aspekt betrifft die vorliegende Erfindung auch Mischungen, die jeweils zumindest eine Verbindung der Formel (Ia) und eine Verbindung der Formel (Ib) umfassen, wobei der Anteil an (Ia) vorzugsweise größer ist als der Anteil an (Ib). In diesen Mischungen paart sich der an Jasminblüten erinnernde Geruch der Verbindungen der Formel (Ia), mit dem jasminig-lactonigen Geruch der Verbindungen der Formel (Ib) in einzigartiger Weise zu einem unverwechselbaren, komplexen Jasmingeruch. Die Substituenten R1, R2 können in der Formel (Ia) die gleiche oder eine andere Bedeutung haben als in Formel (Ib). Wie weiter unten noch anhand des Syntheseweges gemäß Schema I näher erläutert wird, lassen sich die Mischungen umfassend eine Verbindung der Formel (Ia) und eine Verbindung der Formel (Ib), wobei die Substituenten in (Ia) und (Ib) identisch sind, in besonders wirtschaftlicher Weise synthetisieren.According to a further aspect, the present invention also relates to mixtures each comprising at least one compound of the formula (Ia) and a compound of the formula (Ib), wherein the proportion of (Ia) is preferably greater than the proportion of (Ib). In these mixtures, the jasmine flower-like odor of the compounds of the formula (Ia), with the jasmine-lactone odor of the compounds of the formula (Ib) in a unique manner to an unmistakable, complex Jasmingeruch. The substituents R 1 , R 2 may have the same or different meaning in the formula (Ia) as in the formula (Ib). As will be explained in more detail below with reference to the synthesis route according to Scheme I, the mixtures comprising a compound of formula (Ia) and a compound of formula (Ib) wherein the substituents in (Ia) and (Ib) are identical, in synthesize particularly economically.

Zu einer auf 15°C abgekühlten Lösung aus Kalium-fert-butanolat (1.5 Moläquivalente) in DMF (1 ml/mmol Kalium-fert-butanolat), tropft man [2- Alkyliden-3-oxo-cyclopentyl]-essigsäuremethylester (1.0 Moläquivalente), gelöst in DMF (0.5 ml/mmol [2-Alkyliden-3-oxo-cyclopentyl]-essigsäuremethylester). Man lässt 4 Stunden bei Raumtemperatur rühren, bevor man auf 0°C abkühlt und 20%ige wässrige Essigsäure (0.35 ml/mmol [2-Alkyliden-3-oxo-cyclopentyl]- essigsäuremethylester) zügig zugibt. Nach 15-minütigem rühren gibt man etwas Wasser hinzu und extrahiert anschließend dreimal mit Ether. Die vereinigten organischen Phasen werden noch je 1x mit 10%iger NaHCO3-Lösung und Wasser gewaschen, über Na2SO4 getrocknet, abfiltriert und einrotiert. Das erhaltene Rohprodukt wird flashchromatographisch an Kieselgel gereinigt.To a cooled to 15 ° C solution of potassium tert-butoxide (1.5 molar equivalents) in DMF (1 ml / mmol potassium-but-butoxide-ready), is added dropwise [2-alkylidene-3-oxo-cyclopentyl] -acetic acid methyl ester (1.0 molar equivalents ) dissolved in DMF (0.5 ml / mmol [2-alkylidene-3-oxocyclopentyl] -acetic acid methyl ester). The mixture is stirred for 4 hours at room temperature, before cooling to 0 ° C and 20% aqueous acetic acid (0.35 ml / mmol [2-alkylidene-3-oxo-cyclopentyl] - acetic acid methyl ester) rapidly added. After stirring for 15 minutes, add a little water and then extract three times with ether. The combined organic phases are each washed once each with 10% NaHCO 3 solution and water, dried over Na 2 SO 4 , filtered off and concentrated by rotary evaporation. The crude product obtained is purified by flash chromatography on silica gel.
