Facile and Efficient Synthesis of 2-Aminoquinoline Derivatives Reduced by Zn/AcOH
摘要:
In this paper, a simple and efficient method for one-pot synthesis of 2-aminoquinolines was accomplished in good yields via reductive cyclization of nitro and cyano groups mediated by zinc/acetic acid is reported.

A novel and efficient approach to the synthesis of substituted quinoline-1-oxides and the complex compounds SnL2Cl2 (L=2-aminoquinoline-1-oxides) was developed. The reaction has fancy selectivity when 3-(2-nitrophenyl)acrylonitriles were treated with the aid of SnCl2 reagent under the same conditions. When R is -CN or -COOR' the complex compounds SnL2Cl2 (L=2-aminoquinoline-1-oxides) were obtained. Whereas, when R is H or aryl another series of substituted quinoline-1-oxides were formed. The products have been screened for their anticancer activities. (C) 2012 Elsevier Ltd. All rights reserved.
