By using lipase 'PL-266' from Alcaligenes sp. enantioselective acetylation of (±)-albicanol 4 with isopropenyl acetate gave the enantiomerically pure (+)-albicanyl acetate 3 and (+)-albicanol 4. Deprotection of (+)-3 afforded the natural (+)-albicanol 4 which was converted to the natural products (-)-albicanyl 3,4-dihydroxycinnamate 7, (- )-drimenol 8, (-)-drimenin 9 and (-)-ambrox 10.
