摘要：

5-Amino-1,2-azoles react with aromatic and heterocyclic aldehydes, having reactive halogen in ortho-position, and yield pyrazolo[3,4-b;2,3-b]quinolines, bispyrazolo[3,4-b;4',3'-e]pyridines and their heterocyclic analogs, respectively as [1 + 1] or [2 + 1] condensation products. The fluorescent properties of the synthesized compounds are discussed. (C) 2001 Elsevier Science Ltd. All rights reserved.
