Dithiocarbamate and DBU-promoted amide bond formation under microwave condition
摘要:
Dithiocarbamate and DBU-promoted amide bond formation under microwave condition has been reported. The versatility of this synthetic protocol has been demonstrated with various carboxylic acids and different dithiocarbamates. The products thus obtained have been characterized by mp, IR, H-1 NMR, and mass spectroscopy. (C) 2009 Elsevier Ltd. All rights reserved.
A rapid and efficient one-pot method for the synthesis of 2-(N-substituted)-aminobenzimidazoles is described. The reaction is promoted by dithiocarbamate and catalytic CuO. This procedure is general and can be applied to synthesize many potential drug candidates.
