Reaction of 3-Ben zylidenephthalide with Diamines and p-Aminophenylcarboxylic Acids & Antimicrobial Activities of the Products

Abstract

Bis-(2-methylene-3-benzalphthalimidine) II, desoxybenzoin-o-(4'- aminophenyl) carboxamide III and 2- (substitutedpheny1)-3-benzalphthalimidines of type IV and V were obtained via interaction of corresponding diamines with 3-benzylidenephthalide I. Condensation of C6H4 (NH2)2-1,2 with I gave fused Benzimidazoisoindol derivative VII as anomalous product.
