摘要:
The enantioselective synthesis of both the stereoisomers of dihydrokawain-5-ol is described. The key features of the synthetic strategy include (a) Sharpless asymmetric dihydroxylation, (b) Wittig olefination, and (c) formation of beta-keto ester to access the highly enantiomerically pure kavalactones.
