摘要

The total synthesis of the diarylheptanoids (-)-diospongin A (1) and 13 (2) was achieved stereoselectively via the delta-lactone intermediate 6. The key reactions involved are a stereoselective reduction of beta-keto ester and the and Horner-Wadsworth-Emmons and intramolecular oxy-Michael reactions.
