Stereoselective syntheses of trans-fused 6,6-and 6,7-membered ether ring systems having an angular methyl group based on SmI2-induced reductive intramolecular cyclization

摘要

Highly stereoselective syntheses of trans-fused 6,6- and 6,7-membered ether ring systems having an angular methyl group were achieved based on SmI2-induced reductive intramolecular cyclizations of an aldehyde or a methyl ketone and a beta-alkoxy acrylate.
