Enantioselective Total Synthesis of the Proposed Structure of the Endophytic Fungal Metabolite Phomolide G: Structural Revision and Unambiguous Stereochemical Assignment

Abstract A total synthesis of the proposed structure of the natural macrolactone phomolide G ( 1 ) by a bidirectional strategy from L ‐tartaric acid is reported. The ω‐terminus of the molecule was elaborated by nitrile extension, C3‐alkylation and a substrate‐controlled 1,3‐ketone reduction. The α‐terminus was extended by a C 2 aldehyde‐to‐alkenal homologation followed by an auxiliary controlled aldol reaction. Macrolactonization and …
