Syntheses of substituted pyrrolo[2,3-d]imidazole-5-carboxylates and substitued pyrrolo[3,2-d]imidazole-5-carboxylates
Abstract
Starting from readily available p-substituted-benzylamines a series of ethyl 2-alkylthio-1-substituted-ben-zylpyrrolo[2,3-d]imidazole-5-carboxylates was prepared. In addition, starting from 2-alkyl-4(or 5)-formylimidazoles and methyl 4′-bromomethylbiphenyl-2-carboxylate a series of methyl substituted-pyrrolo[2,3-d]imidazole-5-carboxylates and methyl substituted-pyrrolo[3,2-d]imidazole-5-carboxylates was prepared.
