Abstract

Abstract The reaction of substituted (Z)-and (E)-2-arylmethylideneindolin-3 (2H)-ones with malononitrile gave the Micheal addition products which could be cyclised to the corresponding pyrano [3, 2-b] indole. Larger molecules such as cyanoacetic acid and ethyl cyanoacetate failed to react.
