Oxidation reactions of 2′-functionalized 3-aryltetrahydro and 3,4-dihydroisoquinolines

Several 2-functionalized 3-arylisoquinolines in different oxidation stages have been prepared. Fremy's salt or I2/NaAcO oxidation of 2-functionalized 3-aryltetrahydroisociuinolines always stops at the 3,4-dihydroisquinoline stage; however, bett

A common and general access to berberine and benzo [c] phenanthridine alkaloids

The S(RN)1 reactions between o-iodobenzamides and the enolate anion from 2-acetyl homoveratric acid lead to key tricyclic compounds which are easily converted to either berberine or benzo [c] phenanthridine ring systems providing thus a highly-yielding and versatile access to both classes of alkaloids.

BENZOPHENANTHRIDES. XV. SYNTHESIS OF O-METHYLFAGARONINE IODIDE AND CHLORIDE FROM 13α-HYDROXYXYLOPININE

Hydroborination of 3-(2-vinyl-4,5-dimethoxyphenyl)-6,7-dimethoxy-2-methyl-1,2-dihydro-1-isoquinolone gave 3--6,7-dimethoxy-2-methylisoquinolin-1-one, which was converted by the action of various oxidizing agents into a benzophenanthridone derivative. 5-Methyl-5,6-dihydro-2,3,8,9-tetramethoxybenzophenanthridine, obtained from the above benzophenanthridone by reduction with LiAlH4 in tetrahydrofuran at 0 deg C, was converted into O-methylfagaronine iodide by boiling in an ethanolic solution of I2 in the presence of Na acetate.On exchanging I- by Cl-, O-methylfagaronine chloride was obtained in a quantitative yield in boiling methanol with an excess of AgCl.
