Oxidative coupling of dl-N-methylisosalsoline (III) with potassium ferricyanide was carried out, and the structures of the products were determined. It was found that III gives rise both to biphenyl derivatives (VI, VII) and diphenyl ether derivative (IV), and a steric participation of 1-substituent of 2-methyl-6-methoxy-7-hydroxy-1, 2, 3, 4-tetrahydroisoquinoline derivative in the product development in the phenol oxidation reactions was observed.
