An efficient stereoselective synthesis of the C33-C44 fragment of palau'amide is described using a Sharpless asymmetric epoxidation, a regioselective nucleophilic ring opening of the epoxide, a Grignard reaction and a Luche stereoselective reduction of a keto compound as the key steps.

The stereoselective synthesis of the three major fragments (C1-C9, C10-C17, and C19-C26) of an antimitotic marinemacrolide, (-)-dictyostatin, has been achieved with a desymmetrization strategy and Oppolzer syn and anti aldol protocols as the key reactions. Takai olefination and Sonogashira coupling reactions were successfully utilized to establish the 2Z,4E-dienoate portion of the C1-C9 fragment and
