Abstract

Abstract : An efficient ruthenium-catalyzed synthesis of tri-substituted s -triazinones and dihydro- s -triazino[1, 2- a ]benzimidazoles under mild conditions has been developed. Abstract : An efficient ruthenium-catalyzed synthesis of tri-substituted 1, 3, 5-triazinones from alcohols and guanylureas under mild conditions has been developed. The scope of both the alcohols and guanylureas in the reaction is demonstrated. This ruthenium-catalyzed ring-forming process can be successfully extended to 2-guanidinobenzimidazoles to afford substituted dihydro[1, 3, 5]triazino[1, 2- a ]benzimidazoles.
