摘要：
not available for EP1848702of corresponding document: GB2423081 A pro-odorant or pro-flavorant that is liquid at room temperature and has a relatively low viscosity and has the formula (I): wherein R is H, an aliphatic group or an aromatic group, R is an aliphatic group or an aromatic group, provided that the total number of carbon atoms in the groups R and R is 10 or more; R is CN, COOH, COOR, CHO or C(O)R; R, R and R are each independently hydrogen or organic moieties which together with R render a compound of formula RRC=CRR a material having odorant or flavourant characteristics and R and R are each independently an organic moiety; or the formula (II) RRC=NR wherein R has at least 10 carbon atoms and is an aliphatic group or an aromatic group; R and R are each independently H or organic moieties which together with C=O render a compound of formula RRC=O a material having odorant or flavourant characteristics, provided that only one of R and R is hydrogen or the formula (III) wherein R is H, an aliphatic group or an aromatic group, R is an aliphatic group or an aromatic group, provided that the total number of carbon atoms in the groups R and R 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, R is H, alkyl or alkenyl or alkoxy having up to 10 carbon atoms so as to render a compound of formula wherein R has at least 10 carbon atoms and is an aliphatic group or an aromatic group; the or each R is independently a straight or branched chain, saturated or unsaturated hydrocarbyl group or alkoxy group having from 1 to 8 carbon atoms or two groups R together with the carbon atoms to which they are attached form a five or six membered ring which may be saturated or unsaturated (including aromatic) and which may be optionally substituted with from 1 to 3 alkyl groups having from 1 to 6 carbon atoms; and x is from 1 to 5 so as to render a compound of formula a material having odorant or flavorant characteristics. These compounds may be used as flavours and fragrances in a range of compositions, products preparations and articles.
