Concise total synthesis of metacridamides A and B was accomplished through repetitive vinylogous Mukaiyama aldol reactions and ynamide-mediated macrolactonization. Spectral data of both synthetic products were identical to those of the natural products, resulting in the revision of the absolute configuration of the C-9 position to be S .
