Abstract
An iridium-catalyzed enantioselective allylic amination of (E)-cinnamyl and terminal aliphatic allylic carbonates using chiral phosphoramidites as ligands provided branched secondary and tertiary allylic amines in high yields with excellent regio- and enantioselectivity. Reactions in THF displayed the most suitable balance of rate and enantioselectivity.
