Abstract
PURPOSE: To obtain a monoterpene acetate useful as perfume, easily, by reacting a specific unsaturated alcohol with Pb(OAc)4, thereby selectively breaking the C-C side chain.
CONSTITUTION: Monoterpene acetate of formula IV or V, e.g. linalyl acetate of formula II, geranyl acetate of formula III etc., is directly prepared by the reaction of an unsaturated alcohol of formula I [R1=4-methyl-3-pentenyl, 4-methyl-4- pentenyl, etc.; R2=H, CnH2n+1 (n=1-7), CnH2n-1(n=2-7)], e.g. 2,6-dimethyl-2- vinyl- hepten-5-ol-1, with Pb(OAc)4. Then the resulting ester is hydrolyzed to give a monoterpene alcohol, e.g. linalool, geraniol etc.
USE: The alcohol is used as a starting material for the synthesis of, e.g. Vitamine E, Vitamine K, carotin, etc.
