Synthesis of benzo[4,5]imidazo[2,1- a ]phthalazines
摘要:
5,9-Disubstituted benzo[4,5]imidazo[2,1-a]phthalazines are synthesized efficiently from acylbenzoic acids and 2-nitro-5-chlorophenylhydrazine. Nucleophilic substitution in phthalazinones gave a variety of the title compounds after reduction and cyclization. (C) 2003 Elsevier Ltd. All rights reserved.
