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

Apicularen A (1) and related benzolactone acylenamines belong to a growing class of novel natural products possessing highly cytotoxic properties. The challenging structure of 1 includes a 10-membered macrolactone ring, a tetrahydropyran system, an o,m-substituted phenol and a doubly unsaturated acyl group attached on the side chain enamine functionality. The total synthesis of apicularen A described
