2,3,9,10-Tetraoxygenated protoberberin alkaloids, berberine (1a), palmatine (1b), and coptisine (1c) were efficiently converted into the corresponding 12-hydroxy-2,3,10,11-tetraoxygenated protoberberines (6a, 6b, 6c) through an oxidative C8-C8a bond cleav
TRANSFORMATION OF 2,3,9,10-TETRAOXYGENATED PROTOBERBERINE ALKALOIDS INTO 2,3,10,11-TETRAOXYGENATED PROTOBERBERINE ALKALOIDS

, p. 2927 - 2930 (2007/10/02)
2,3,10,11-Tetraoxygenated tetrahydroprotoberberine (6) were synthesized from the corresponding 2,3,9,10-tetraoxygenated protoberberine alkaloids (1) through oxidative C8-C8a bond cleavage, photocyclization, and deoxygenation.
