A one-pot enantioselective cyclopropanation process involving 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 on Michael acceptors. This process achieves high enantioselectivities ranging from 90% to over 99%. Its application to the formation of the main core of presilphiperfolan-1β-ol, a sesquiterpene, is described.
