Abstract
NEW MATERIAL:δ-(4-Pentenyl)-δ-lactone of formula I.
USE: A perfumery having sweet, moderate and mild butter-like flavor. It can be compounded to various perfumery composition such as flavor for fruit essence, margarine, chocolate, cracker, etc. perfume for soap, etc.
PROCESS: An unsaturated alcohol of formula II is reacted with oxalic acid dichloride in the presence of dimethyl sulfoxide to obtain an unsaturated ketone of formula III, which is subjected to Michael addition reaction with dimethyl malonate in the presence of a basic condensing agent. The ketodiester thus prepared is reduced with NaBH4 to a hydroxydiester of formula IV, which is then converted to a hydroxy acid of formula V by saponification and decarboxylation. Dehydrative cyclization of the compound of formula V yields the objective compound of formula I. A perfumery composition is prepared by the use of 0.01W100wt% of the compound of formula I as an active component.
