Abstract

An organocatalytic enantioselective synthesis of α-(benzylamino)cyclobutanones has been achieved by employing a tandem condensation/intramolecular rearrangement/proton transfer reaction and starting from racemic α-hydroxycyclobutanone and a selection of benzylamines. This reaction sequence afforded the products in good to high yields with moderate to high enantioselectivities. An organocatalytic enantioselective synthesis of α-(benzylamino)cyclobutanones has been achieved by employing a tandem condensation/intramolecular rearrangement/proton transfer reaction. The reaction sequence began from readily available racemic α-hydroxycyclobutanone and a variety of benzylamines to afford the products in good to high yields and with moderate to high stereoselectivities.
