摘要
(-)-Dihydroedulan II and related compounds were synthesized from (2R,1'Rs)-dihydro-alpha-ionol, which was prepared by lipase-catalyzed enantioselective transesterification of the corresponding diastereomeric mixture as the key-step. Fungal allylic oxidation of (-)-dihydroedulan II worked well to afford a corresponding alcohol as well as (+)-dihydroedulan-8-one.
