Abstract

beta-Terpineol, a minor constituent of commercial terpineol as well as some essential oils, is a mixture of cis and trans isomers, separation of which by physical or chemical methods is laborious. A direct, simple synthesis of trans-beta-terpineol from (+)-limonene via its trans-1,2-oxide is described in which (+)-limonene is reacted with N-bromosuccinimide in acetone solution to yield (1S, 2S 4R)-2-bromo 1-hydroxy-P-menth-8-ene. This is then transformed to the epoxide in the presence of a base and the epoxide is reduced using lithium aluminium hydride to give trans-beta-terpineol exclusively.
