Selective mono-aza-Michael additions of divinyl ketones with 3-(arylimino)indolin-2-ones in the presence of cesium carbonate are described. N-Enone-functionalized 3-(arylimino)indolin-2-ones were efficiently synthesized in satisfactory yield. The salient features of this protocol are high regioselectivity, high yield, and mild conditions.
