Enantioselective construction of trifluoromethylated quaternary stereocenters via Rh-catalyzed asymmetric dehydrated arylation of unprotected hemiaminals
Abstract
A highly enantioselective Rh-catalyzed dehydrated arylation of unprotected hemiaminals has been developed, providing a series of chiral benzosultams bearing trifluoromethylated quaternary stereocenters in high yields with excellent enantioselectivities (up to 99% ee). The synthetic utility was further demonstrated by the facile enantioselective construction of a HIV-1 inhibitor molecule.
