Abstract

Abstract-The reaction of 8-(triphenylphosphoimino) quinoline with aryl aldehydes gave 2- aryI-4#-imidazo [4, 5, l-i7] quinolines. In the reaction, tandem aza-Wittig reaction and cyclization attended with hydride shift occurred. The reaction of 8-(triphenylphosphoimino) quinoline with aryl isocyanates gave l, 3-diaryl-l, 2, 3, 9a-tetrahydro [l, 3, 5] triazolo [2', 3': 2, l; 3', 4'-a] imidazo [4, 5, l-//] quinolin-2-ones (11) and 2-(arylamino) imidazo [4, 5, l-(/] quinolin ...
