A facile synthesis of pyrrolo[1,2-a]benzimidazoles and pyrazolo[3,4:4′,3′]pyrrolo[1,2-a]benzimidazole derivatives
摘要:
Reaction of 2-cyanomethylbenzimidazole 1 with hydrazonoyl halides 2 led to formation of pyrrolo[1,2-a]benzimidazole derivatives 7. Similar reaction of I with halides 3 afforded 5-amino-4-(benzimidazol-2-yl)pyrazole derivatives 11 or 1-amino-2-arylpyrazolo[3,4:4',3']pyrrolo[1,2-a]benzimidazol-4-one 14 depending on the reaction conditions. The mechanisms of the studied reactions are discussed. (C) 2003 Elsevier Ltd. All rights reserved.
