Abstract
A method of selective conversion of Abienol, represented by formula 1, to Sclareodiol, represented by formula 2 by ozonolysis and subsequent reduction. The ozonolysis is carried out at temperatures above −60° C., preferably in nonhalogenated solvents. R is selected from H, acetals, aminals, optionally substituted alkyl groups, such as benzyl group, carboxylates such as acetates or formates, carbonates such as methyl or ethyl carbonates, carbamates, and any protecting group which can be attached to 1 and cleaved from 2, R' is selected from CH═CH, an alkyl moiety with C2-C20, e.g. CH—CH, or a cycloalkyl or polycycloalkyl moiety with C3-C20, e.g. cyclopropyl, optionally alkylated, respectively, and the wavy bond is depicting an unspecified configuration of the adjacent double bond between C2 and C3.
