A BIOMIMETIC SYNTHESIS OF -CORYNOLINE, -11-EPICORYNOLINE, -ISOCORYNOLINE, AND -EPIISOCORYNOLINE FROM CORYSAMINE

A novel and efficient synthesis of hexahydrobenzophenanthridine alkaloids, -corynoline, -11-epicorynoline, -isocorynoline, and -11-epiisocorynoline was accomplished from protoberberine alkaloid, corysamine through a biogenetic route.
