At last,a convergent and general protocol to marine natural product,as demonstrated by the enantioselective total synthesis of malyngamides O,P,Q,R, 5"-epi-Q and 5"-epi-R bearing terminal vinylic chloride structure,was developed in detail.E,(7S)-7-methoxytetradec-4-enoic acid was prepared using the above described Johnson-Clainsen rearrangement,the terminal vinyl chloride was constructed using Wittig reaction as key step,the pyrrolidone derivative was constructed using L-serine as natural chiral pool.Starting from the synthesis of malyngamides O and P to explore the general route,an aldol reaction of methyl acetate with the vinyl chloride part in the presence of LDA gave the skeleton of amine portion,followed by amidation with the fatty acid finished the synthesis of malyngamide P.
