Organocatalytic asymmetric allylic amination of Morita-Baylis-Hillman carbonates of isatins

Abstract

The investigation of a Lewis base catalyzed asymmetric allylic amination of Morita-Baylis-Hillman carbonates derived from isatins afforded an electrophilic pathway to access multifunctional oxindoles bearing a C3-quaternary stereocenter, provided with good to excellent enantioselectivity (up to 94% ee) and in high yields (up to 97%). © 2012 Zhang et al.
