Rearrangement of benzylaminonitriles to give cyclohepta[c]pyrrol-6(2H)-ones
Abstract
N-4-Methoxybenzyl- and N-3,4-dimethoxybenzyl-aminoacetonitriles with both 2-aryl and N-alkyl substituents undergo O-demethylation and rearrangement with elimination of ammonia in concentrated sulphuric acid to give 1-aryl-N-alkylcyclohepta[c]pyrrol-6(2H)-ones.
