To enable the large-scale synthesis of coibamide A, we developed an improved synthetic strategy for this class of cyclodepsipeptide. The versatility of the synthetic procedure was demonstrated by the preparation of a series of designed coibamide A analogues, which enabled the preliminary structure–activity relationship (SAR) studies for this compound. Although most modifications of coibamide A resulted
The synthesis of dolastatin G (1) and nordolastatin G (2), new cytotoxic cyclodepsipeptides from the Japanese seahareDolabellaauricularia, was achieved enantioselectively, and the present result confirmed their stereostructures unambiguously.
