Stereochemistry of an oxidative 1,4-fragmentation of γ-stannyl alcohols with a hypervalent organoiodine compound and the synthesis of erythro-6-acetoxyhexadecan-5-olide

Abstract

Iodine(III)-mediated oxidative 1,4-fragmentation of the 2,3-trans- and 2,3-cis-3-stannyl alcohols, (6a,b) and (6c), proceeds stereospecifically to give the E- and Z-enals, (7) and (8), respectively, and stetreoselective synthesis of the mosquito pheromone, erythro-6-acetoxyhexadecan-5-olide (5), starting from the E-enal(7), was accomplished.
