A New General Approach for the Synthesis of 2-Substituted-3H-indol-3-one N-Oxide Derivatives

Abstract

2-aryl (phenyl, 1,3-benzodioxolyl) and 2-alkyl (ethyl, sec-butyl)-3H-indol-3-one N-oxides were synthesized by a new general method involving a reductive intramolecular cyclization reaction of ortho-diketo nitrobenzene derivatives.
