Total synthesis of the polyene macrolide antibiotic roxaticin. I. Synthesis of the polyol fragment of roxaticin using a four-carbon chain extension strategy
The C11–C26 polyol fragment of roxaticin containing eight chiral centers has been prepared in a reiterative manner using coupling reactions of chiral dithianes and epoxides followed by stereoselective reduction.

Synthesis of Southern (C1'-C11') and Eastern (C8-C18) Fragments of Pamamycin-607, an Aerial Mycelium-inducing Substance of Streptomyces alboniger
Synthesis of the southern C1'-C11' and eastern C8-C18 fragments of pamamycin-607, an aerialmycelium-inducingsubstance of Streptomycesalboniger, was achieved. The southern fragment was synthesized by using the Evans aldol reaction and cis-selective iodoetherification as the key steps in a 9.6% overall yield (7 steps). The eastern fragment was constructed via the Julia coupling reaction and cis-selective

The synthesis of a C(1)–C(24) advanced southern hemisphere fragment towards the totalsynthesis of spirastrellolide E has been achieved. Highlights of the route include a highly convergent Type I Anion Relay Chemistry (ARC) tactic for fragment assembly, in conjunction with a directed, regioselective gold-catalyzed alkyne functionalization to generate the central unsaturated [6,6]-spiroketal.
