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.

AbstractMass spectral fragmentation pathways were formulated for 1‐alkylisatins, 1‐alkyl‐3‐arylimino‐2‐indolinones and 3‐arylimino‐2‐indolinons bearing no substituent at the 1‐position. Deuterium‐labelled and 13C‐labelled compounds were utilized in this study. An interesting rearrangement of the 1‐alkyl compounds, in which the 1‐alkyl substituent is incorporated into a fulvene ion, was established.
