A new iron(III)-salen catalyst for enantioselective Conia-ene carbocyclization.

Subrata Shaw1, James D White.   

Abstract

A chiral iron(III)-salen complex based on a cis-2,5-diaminobicyclo[2.2.2]octane scaffold catalyzes asymmetric Conia-ene-type cyclization of α-functionalized ketones containing an unactivated terminal alkyne and produces an exo-methylenecycloalkane possessing a stereodefined quaternary center.
