The synthesis of stevastelinB3 (2) and B (5) are described. In a first approach, epoxy cyclodepsipeptide 8 was considered as a promising candidate for the synthesis of the [15]-membered ring members of the stevastelins; however, the oxirane ring opening, required for the completion of the natural stevastelinsynthesis, failed. Thus, we synthesized stevastelinB (5), carrying out the oxirane ring opening
