One-pot multi-component reactions (MCRs) by virtue of their convergence, productivity , facile execution, and high yield have attracted considerable attention in recent years.MCRs have been also considered as one of the most efficient methods to construct heterocyclic compounds from simple starting materials in a single operation.As part of a continuing effort in our laboratory toward the developmen t of new multi-com ponent condensation reactions ,and the development of mild and practical protocols for the synthesis of useful heterocyclic compounds ,herein we wish to report that a three-component condensation reaction can becarried out effectively to obtain 3-(1H-benzo[d]imidazol-1- yl)isoindolin-1- one derivatives in satisfactory yields using phthalaldehydic acid, primary amine, and 2-mercapto benzimidaz ole or 2-hydrox ybenzimidazole as the starting materials. To the best of our knowledge, this is the first report for the synthesis of 3-(1H-
benzo[d]imidazol-1- yl)isoindolin-1-one derivatives (Scheme 1).
