NEW MATERIAL:A compound of formula I [R and R<1>, are H, or -COR<2> (R<2> is H, alkyl, or alkenyl group); except where R and R<1> are H; R<1> is H; and R is -COCH3]. EXAMPLE:3-Hydroxy-cis-5-octen-1-yl-propionate. USE:Flavor enhancers for durable fragrance and modifiers, having apple plavor and fragrance. PROCESS:A compound of formula II (R<3> is H or -COCH3) is reacted with a carboxylic acid of formula III (X is OH, Halogen, or O; n is 1 when X is OH, and n is 2 when X is O), or its functional derivative to give the compound of formula I. |
