摘要

(±)-4′-Iodoindolmycenate 6 was stereoselectively converted into the (±)-(2, 3)-syn-2- thioacetoxy ester 16 with retention of C2-stereochemistry in (±)-6. Palladium-catalysed cyclisation of indolyl iodide and the internal C2 thiol group of the substrate (±)-17 derived from (±)-16 gave the (±)-cis methyl ester 2 of natural chuangxinmycin (1).
