A protocol for the synthesis of a series of indole-1-carboxamides was reported via the N-arboxamidation of indole derivatives with aryl (alkyl) isocyanates catalyzed by 5.0 mol% cesium hydroxide monohydrate (CsOH·H2O). This method is suitable for different indole derivatives and aryl (alkyl) isocyanates, for giving corresponding products in excellent yields. Compared to the reported methods, this protocol has the advantages of mild reaction conditions, wild functional group tolerance, simple operation and excellent yields. An efficient route to indole-1-carboxamides is previded.

Key words: cesium-catalyzed N-arboxamidation, indole-1-carboxamides, indole derivatives, aryl (alkyl) isocyanates
