Amide-Catalysed Isomerisation of 5,6-Dihydroisoquinolines: a Novel Synthesis of 1,2-Dihydroisoquinolines

Knoevenagel condensation of 2-acylcyclohexanones or 2-ethoxycarbonylcyclohexanone with either cyanoacetamide or malononitrile followed by silver salt alkylation gave the 5,6,7,8-tetrahydroisoquinolines (3a-i).Chromic acid oxidation of the 5,6,7,8-tetrahyd
