A Ru(iii) – catalyzed α-cross-coupling aldol type addition reaction of activated olefins with isatins†
Abstract
A α-cross-coupling aldol type addition reaction activated olefins with isatins has been described in the presence of ruthenium(III) chloride and tributyltin hydride (TBTH) at room temperature. This method is found to work consistently for the delivering of ene-carbonyl coupled products in good to excellent yields with moderate to acceptable selectivity. The substrate scope of the present method was briefly discussed.
