One-Pot Enantioselective Cyclopropanation Process from Inactivated Aldehydes Mediated by Organocatalysis

Abstract

A synergistic combination of organocatalysis and N-Iodosuccinimide allows for the asymmetric formation of cyclopropanes through the direct C-H activation of aldehydes onMichael acceptors. This process achieves high enantioselectivities ranging from 90% to over 99%. An application to the formation of the main core of presilphiperfolan-1β-ol, a sesquiterpene, is described.
