Iron-catalyzed cascade C–C/C–O bond formation of 2,4-dienals with donor–acceptor cyclopropanes: access to functionalized hexahydrocyclopentapyrans

Abstract

Iron-catalyzed cascade C–C and C–O bond formation of 2,4-dienals with donor–acceptor cyclopropanes (DACs) has been developed to furnish hexahydrocyclopentapyrans. Optically active DACs can be coupled stereospecifically (>97% ee). Chirality transfer, use of iron-catalysis and substrate scope are the salient practical features.
