A concise, highly efficient total synthesis of (−)-salicylihalamide A (1), a novel marine sponge metabolite, has been achieved. Key features of the synthetic strategy include a highly E-selective ring-closing metathesis to construct the 12-membered salicylihalamide A macrocycle and a practical method for installation of the labile ene-hepta-(Z,Z)-dienamide side chain involving N-acylation of enecabarmate
