Toward the total synthesis of Luminamicin: construction of 14-membered lactone framework possessing versatile enol ether moiety

Abstract

Luminamicin (1) was found to exhibit selective antibacterial activity against anaerobic bacteria by our group in 1985. The concise structure of 14-membered lactone of 1 was synthesized. Construction of a versatile enol ether moiety was achieved by Stille cross coupling via hydrostanylation of the ethynyl ether, and a maleic anhydride moiety was derived from the furan constitution by the oxidation after the macrolactonization at a late-stage.
