Phenolic Oxidative Coupling Reaction of 1, 2, 3, 4-Tetrahydro-7-hydroxy-1-(2-hydroxy-4, 5-methylenedioxybenzyl)-6-methoxy-2-methyl-isoquinoline with Ferric Chloride (Studies on the Syntheses of Heterocyclic Compounds. CCLXV)

Abstract

Phenolic oxidation of 1, 2, 3, 4-tetrahydro-7-hydroxy-1-(2-hydroxy-4, 5-methylenedioxybenzyl)-6-methoxy-2-methylisoquinoline (Ib) afforded the dienone (IIb) in 3.2% yield, which was characterized by its microanalysis and spectral determination.
