Abstract

The rhodium-catalyzed regio- and enantioselective amination of racemic tertiary allylic trichloroacetimidates with a variety of aniline nucleophiles is a direct and efficient route to chiral α,α-disubstituted allylic N-arylamines. We describe the first dynamic kinetic asymmetric transformations of racemic tertiary allylic electrophiles with anilines utilizing a chiral diene-ligated rhodium catalyst. The method allows for the formation of α,α-disubstituted allylic N-arylamines in moderate to good yields with good to excellent levels of regio- and enantioselectivity.
