Total synthesis of the proposed structure of a polyketide from Phialomyces macrosporus

Abstract

Total synthesis of the proposed structure of a polyketide isolated from Phialomyces macrosporus is described. The synthesis involved chemoselective epoxidation, regioselective epoxide ring opening, chemo- and diastereoselective dihydroxylation, and vinylation of lactone accompanied by the formation of a furan ring.
