[RTl2SI]2NH[RTl 2 SI] 2 NH
mit Ammonlumsulfamat. Diese Umsetzung geht im einzelnen aus DE-OS 27 11 091 hervor.
Jede organische oder Organoslliclumverbindung mit wenigstens einer an Kohlenstoff oder an Silicium
gebundenen OH und/oder NH-Gruppe im Molekül kann nach dem erfindungsgemäß zu verwendenden
Mittel sllyllert werden. Beispiele für solche organische und Organosiliclumverblndungen sind Alkohole, wie
Isopropanol, n-Hexanol, Octadecanol und Benzylalkohol,
Glycole und Polyglycole, wie Äthylenglycol und Hydroxyendgruppen enthaltende Poly(alkylenoxlde),
Phenole wie Phenol selbst, m-KresoI, p-Xylenol, Pyrogallol
und 2,6-Dl-sek.-butylphenol, Mono- und Polycarbonsäuren, wie Essigsäure, Propionsäure, Benzoesäure,
Oxalsäure, Malonsäure und Maleinsäure, Amine wie Äth)Iendlamln, Dläthylentrlamln und Anilin und Silanole
und Siloxanole, wie Dlphenylsllandlol und 1,3-Dlmethyl-l,3-dlphenyl-dislloxandiol-l,3.
Erflndungsge-with ammonium sulfamate. This implementation can be seen in detail from DE-OS 27 11 091.
Any organic or organosilicon compound with at least one OH and / or NH group bonded to carbon or silicon in the molecule can be silylated according to the agent to be used according to the invention. Examples of such organic and organosilicon compounds are alcohols such as isopropanol, n-hexanol, octadecanol and benzyl alcohol, glycols and polyglycols such as ethylene glycol and poly (alkylene oxides) containing hydroxyl end groups, phenols such as phenol itself, m-cresol, p-xylenol, and pyrogallol , 6-Dl-sec.-butylphenol, mono- and polycarboxylic acids, such as acetic acid, propionic acid, benzoic acid, oxalic acid, malonic acid and maleic acid, amines such as eth) iendlamine, diethylenetrlamine and aniline, and silanols and siloxanols such as diphenylsilandlol and 1,3-dimethylol -l, 3-dlphenyl-dislloxanediol-l, 3. Invention
ss maß lassen sich vor allem biologisch aktive Substanzen oder Ihre Vorläufer sllylleren, wie Penicilline und Steroide. Hierbei Ist die zu silyHerende Gruppe gewöhnlich eine OH-Gruppe In Form einer Carboxylgruppe (-CO.OH) oder einer -C.OH-Gruppe. Von der Erflndung kann daher beispielsweise mit Vorteil Gebrauch gemacht werden zur schützenden Sllyllerung von Penicillin G während seiner Überführung In 6-Amlnopeniclllansäure, zur schützenden Sllyllerung von 6-Amlnopenlclllansäure während ihrer Überführung In 6-Acylamldopenlclllansäuren und zur schützenden Sllyllerung von 7-Aminocephalosporansäure und 7-Amldodesacetoxycephalosporansäure während Ihrer Überführung In 7-AcylamldocephalosporansSuren und 7-Acylamldodes-Above all, biologically active substances can be used or their precursors such as penicillins and steroids. Here the group to be established is common an OH group in the form of a carboxyl group (-CO.OH) or a -C.OH group. From the invention can therefore be used to advantage, for example, for the protective synthesis of penicillin G during its conversion into 6-aminopenicllanic acid, for the protective silylation of 6-aminopenic acid during its conversion into 6-acylamdopenic acid and for the protective synthesis of 7-aminocephalosporanic acid and 7-amldodeacetoxycephalosporanic acid during your transfer to 7-acylamldocephalosporan acids and 7-acylamldodes-
acetoxycephalosporansäuren. Weiter kann die Erfindung beispielsweise auch Anwendung finden bei der Überführung von ö-Acylamidopenlclllansäuresulfoxiden in 7-Acylamldodesacetoxycephalosporansäuren und der Herstellung der Silylester von Azetidin-2-sulfinaten. ■acetoxycephalosporanic acids. The invention can also for example also find application in the conversion of δ-acylamidopenlclllansäuresulfoxiden in 7-acylamldodesacetoxycephalosporanic acids and the Preparation of the silyl esters of azetidine-2-sulfinates. ■
Zur Durchführung der Silyierung können die erfindungsgemäß als Sicherungsmittel dienenden Sulfamatverbindungen und die zu silylierenden Verbindungen in den verschiedensten Verhältnissen eingesetzt wenden. Die im Einzelfall angewandten Verhältnisse hängen in einem gewissen Maß von dem gewünschten Silylierungsgrad ab. Wenn man alle vorhandenen OH und/oder NH Gruppen silylieren möchte, dann wird das Sulfamat vorzugsweise in einem stöchiometrischen Überschuß angewandt. iäThe sulfamate compounds which serve as securing agents according to the invention can be used to carry out the silyation and the compounds to be silylated are used in a wide variety of ratios. The ratios used in the individual case depend to a certain extent on the desired degree of silylation away. If you want to silylate all existing OH and / or NH groups, then the sulfamate is preferably used in a stoichiometric excess. iä
Die erfindungsgemäße Silylierungsreaktion kann in Gegenwart oder Abwesenheit eines Verdünnungsmittels durchgeführt werden. Verdünnungsmittel, die falls erwünscht, verwendet werden können, sind inerte organische Lösungsmittel, wie Toluol, Xylol, Benzol, Hexan, Dichlorreeuian und Dimethylformamid. Ein Nebenprodukt der Silylierungreaktion Ist Sulfaminsäure. Diese Verbindung ist in den meisten organischen Lösungsmitteln unlöslich und kann deshalb bei Verwendung eines geeigneten organischen Lösungsmittels leicht durch Abgießen oder Filtrieren entfernt werden.The silylation reaction according to the invention can be carried out in the presence or absence of a diluent be performed. Diluents which can be used if desired are inert organic Solvents such as toluene, xylene, benzene, hexane, dichloroethane and dimethylformamide. A By-product of the silylation reaction is sulfamic acid. This compound is insoluble in most organic solvents and can therefore be used in Use of a suitable organic solvent easily removed by pouring or filtering.
In vielen Fällen setzt die Reaktion nach dem Vermischen des Suifamats und der zu silylierenden organischen und/oder Organoslliclumverbindung spontan ein. Wenn erwünscht können jedoch auch zur Beschleunigung der Reaktion und/oder zur Erleichterung der Gewinnung des Reaktionsprodukte e'"/öhte Temperaturen, zum Beispiel von 30 bis 140° C angewandt werden.In many cases the reaction continues after the suifamate and the organic to be silylated have been mixed and / or organosilicate compound spontaneously. If desired, however, it can also be used for acceleration the reaction and / or to facilitate the recovery of the reaction products e '"/ ohte temperatures, for example from 30 to 140 ° C can be used.
Silyllerungsreaktionen werden häufig ;am Schutz von OH- und/oder NH-Gruppen während organischer Synthesen angewandt. Hierbei ist es üblich, die SiIyI-gruppe durch Umsetzung mit Wasser von der organischen Verbindung zu entfernen. In dieser Stufe als Nebenprodukt etwa vorhandene Sulfaminsäure kann von dem Reaktionsgemisch in wäßriger Lösung entfernt und danach, falls erwünscht durch Erwärmen dieser Lösung oder durch Stehenlassen derselben, In Ammonlumblsulfat Obergeführt werden.Silylation reactions are frequent; at the protection of OH and / or NH groups applied during organic syntheses. Here it is common to use the SiIyI group to be removed from the organic compound by reaction with water.

[(CH3)3SiLNSO2-O-Si(CH3)3 wird nach der Methode von Becke-Goehring et al., Annalen, Bd. 618, S. 43 bis 52 (1958) hergestellt. 4,70 g (0,015 Mol) dieser Verbindung und 1,82 g (0,010 MeI) 2,6-Dl-sek.-butylphenol werden in einem bei 24° C gehaltenen verschlossenen Kolben miteinander vermischt. Es bildet sich sofort ein weißer Niederschlag. Nach 15 Minuten wird das Reaktionsgemisch durch Gasflüssigkeitschromatographie untersucht, wofür eine 183 χ 0,64 cm messende Säule verwendet wird, die mit einem hochviskosen Diorganopolyslloxan auf Diatopart S. als Träger gefüllt Ist. Die chromatographische Säule wird mit einer Geschwindigkeit von 20°C/Minute von 700C auf 300° C erwärmt. Dabei wird eine einzige Spitze mit einer Verweilzeit von 8,90 Minuten, die dem 2,6-Di-sek.-butylphenoxytrimethylsilan entspricht, erhalten, woraus sich ergibt, daß die Siiylierung innerhalb von 15 Minuten praktisch vollständig ist.[(CH 3 ) 3 SiLNSO 2 -O-Si (CH 3 ) 3 is prepared according to the method of Becke-Goehring et al., Annalen, Vol. 618, pp. 43 to 52 (1958). 4.70 g (0.015 mol) of this compound and 1.82 g (0.010 mol) 2,6-Dl-sec-butylphenol are mixed with one another in a sealed flask kept at 24 ° C. A white precipitate forms immediately. After 15 minutes, the reaction mixture is examined by gas-liquid chromatography, for which a column measuring 183 χ 0.64 cm is used, which is filled with a highly viscous diorganopolyslloxane on Diatopart S. as a carrier. The chromatographic column is heated at a rate of 20 ° C / minute from 70 0 C to 300 ° C. A single peak with a residence time of 8.90 minutes, which corresponds to 2,6-di-sec-butylphenoxytrimethylsilane, is obtained, from which it follows that the silylation is practically complete within 15 minutes.
