synthetic route to a class of marine natural products—malyngamides O (1), P (2), Q (3), R (4), 5′′-epi-3 and 5′′-epi-4—bearing a novel vinyl chloride structural motif was developed. The key steps involved construction of the vinyl chloride functionality by Wittig reaction, a DCC/HOBt-promoted amidation, an aldol reaction in the construction of the basic backbone of 1, 2, 3, 4, 5′′-epi-3, and 5′′-epi-4
