Abstract

A three-component, one-step method for the synthesis of 4-alkyl-3-aryl-2, 6-dicyanoanilines involving reaction of alkyl aldehyde, malononitrile and aryl aldehyde in presence of morpholine is reported. Highly functionalized 2, 3, 5, 6, 7-and 2, 3, 4, 5, 7-substituted indoles were prepared from these dicyanoanilines by reaction with ethyl bromoacetate. These substituted dicyanoanilines and indoles have a potential to be converted into various ...
