Document Type and Number:
WIPO Patent Application WO2006085049
Kind Code:
A3
Abstract:
A pro-odorant or pro-flavorant having the formula (I): wherein R1 is H, an aliphatic group or an aromatic group, R2 is an aliphatic group or an aromatic group, provided that the total number of carbon atoms in the groups R1 and R2 is 10 or more; R3, R4 and R6 are each independently hydrogen or organic moieties which together with C(O)R5 render a compound of formula R5C(O)R6C=CR3R4 a material having odorant or flavourant characteristics and R5 is hydrogen or an organic moiety; or having the formula (II): R8R9C=NR10 wherein R10 is an aliphatic group or an aromatic group having at least 10 carbon atoms; R8 and R9 are each independently hydrogen or organic moieties which together with C=O render a compound of formula R8R9C=O a material having odorant or flavourant characteristics, provided that only one of R8 and R9 is hydrogen; or having the formula (III): wherein R1 is H, an aliphatic group or an aromatic group, R2 is an aliphatic group or an aromatic group, provided that the total number of carbon atoms in the groups R1 and R2 is 10 or more; Z is CH2 or O, n is 0 or 1, such that the ring is a 5 or 6 membered ring, R11 is alkyl or alkenyl having up to 10 carbon atoms so as to render a compound of formula (IV): a material having odorant or flavorant characteristics is described. Methods for producing these compounds and their use as flavours and fragrances is also described.
