β¦ Synopsis
An electrochemical methodology offering efficient access to mediates. Under slightly basic conditions, these undergo spontaneous ring-contraction to produce the N-substituted N-alkyl-and N-aryl-substituted 1-aminoindoles has been developed.
N-Substituted 2-(ortho-nitrosophenyl)ethyl-heterocycles in good yields. The reactions have been studied in slightly acidic and slightly basic aqueous alcoholic media. amines, electrogenerated in a "redox" flow cell, undergo intramolecular cyclization to hydrocinnoline-type interlibrium depends on the attached substituents.
