The present application relates to a new derivative of butane thiol, its preparation process, its application in particular in perfumery and the compositions containing it.
On connaît déjà le 1-méthoxy 3-méthyl 3-butane thiol isolé à partir de bourgeons de cassis. We already know 1-methoxy 3-methyl 3-butane thiol isolated from blackcurrant buds.
Ce dérivé est responsable de la composante olfactive dite "d'urine de chat" de l'arôme de cassis. This derivative is responsible for the so-called "cat urine" olfactory component of blackcurrant aroma.
La préparation par extraction d'un tel dérivé a été décrite notamment dans le brevet français N 85.14680. The preparation by extraction of such a derivative has been described in particular in French patent N 85.14680.
La Demanderesse a découvert que ltéthoxy-4 méthyl-2 butane thiol-2 est doté de propriétés interessantes : à dilution appropriée, il a une remarquable odeur de même qu'un seuil de perception olfactive très bas. The Applicant has discovered that 4-ethoxy-2-methyl-2-butane thiol-2 has interesting properties: at appropriate dilution, it has a remarkable odor as well as a very low olfactory perception threshold.
Rien dans l'art antérieur ne décrit ni ne suggère ltéthoxy-4 méthyl-2 butane thiol-2, d'autant que les dérivés homologues portant un radical propoxy ou butoxy sont dotés d'une note typique d'urine de chat/cassis beaucoup moins intense que celle de ltéthoxy-4 méthyl-2 butane thiol-2. De plus, le seuil de perception olfactive de ces homologues, est largement supérieur à celui dudit dérivé. Nothing in the prior art describes or suggests ltethoxy-2-methyl-2-butane thiol-2, especially since the homologous derivatives carrying a propoxy or butoxy radical are endowed with a typical note of cat urine / blackcurrant much less intense than that of 4-ethoxy-2-methyl-2-butane thiol.

which is reduced to obtain a derivative of formula (III)
which is reacted with an ethyl halide to obtain the derivative of formula (IV)
debenzylated to obtain the 4-ethoxy-2-methyl-2-thiol butane expected.
La réaction du sénécioate de méthyle avec le benzylmercaptan est réalisée de préférence en présence de
Triton B.The reaction of methyl senecioate with benzylmercaptan is preferably carried out in the presence of
Triton B.
La réduction du dérivé de formule (II) peut être réalisée par exemple par action d'un métal alcalin, de préférence le sodium dans un alcanol anhydre tel que l'éthanol, mais on utilise avantageusement un hydrure tel que 1 'hydrure d'aluminium-lithium. The reduction of the derivative of formula (II) can be carried out for example by the action of an alkali metal, preferably sodium in an anhydrous alkanol such as ethanol, but a hydride such as aluminum hydride is advantageously used. -lithium.
La réaction du dérivé de formule (III) avec l'halogénure d'éthyle est avantageusement réalisée après activation du dérivé de formule (III) par un hydrure alcalin, de préférence l'hydrure de sodium. The reaction of the derivative of formula (III) with ethyl halide is advantageously carried out after activation of the derivative of formula (III) with an alkaline hydride, preferably sodium hydride.
La débenzylation se fera avantageusement par action d'un métal alcalin, notamment le sodium, dans l'ammoniac liquide. Debenzylation will advantageously be carried out by the action of an alkali metal, in particular sodium, in liquid ammonia.
A dilution appropriée, l'éthoxy-4 méthyl-2 butane thiol-2 possède, de manière remarquable, la note typique dite d'urine de chat présente dans l'arôme de cassis -
Cette composante de l'odeur, ainsi que l'arôme de cassis peuvent trouver de remarquables applications, respectivement en parfumerie et dans l'aromatisation des aliments.
