The total synthesis and an unambiguous structure confirmation of stevastelin B 1, a novel 15-membered cyclic depsipeptide, are described; the fatty acid moiety in 1, prepared stereoselectively from L-quebrachitol was converted into the amino carboxylic acid, whose macrolactamization by Shioiriâs procedure effectively constructed the cyclic structure of 1.

Total Synthesis of Stevastelins: Structure Confirmation of Stevastelins B and B3, and Structure Revision of Stevastelin C3
peptide and subsequent macrolactamization gave stevastelinB. Stevastelins C3 and B3 were also synthesized by a similar way. The direct comparison of synthetic stevastelins with natural compounds revealed that the synthetic stevastelinsB and B3 are identical to the natural products, confirming the proposed structures. However, the synthetic stevastelin C3 was found to not be identical with the natural
