Efficient Total Syntheses and Structural Verification of Both Diospongins A and B via a Common δ-Lactone Intermediate
摘要:
The total syntheses of the two aryl C-glycoside natural products diospongins A and B are described. The key reactions involved stereoselective reductions of the appropriate oxocarbenium cations that were derived from a common delta-lactone intermediate.
