Benzo[c]phenanthridine alkaloids fromCorydalis incisa

Archives of Pharmacal Research, 2000
Six benzo[c]phenanthridine alkaloids, corynoline (1), acetylcorynoline (2), corynoloxine (3), luguine (4), 6-oxocorynoline (5), and 12-hydroxycorynoloxine (6) were isolated from the aerial parts of Corydalis incisa, and 6 was isolated for the first time from nature. The structure was elucidated by NMR techniques.

Synthèse Dans La Série Des Phenanthridines. IV. Préparation De Nouveaux Radioprotecteurs A Motif Phenanthridine

Bulletin des Sociétés Chimiques Belges, 1991
AbstractNew phenanthridines substituted in the 6‐position by a β‐aminoethylthiol chain have been synthesized. These new products are easily obtained from 6‐methylphenanthridine by a Mannich reaction or from 6‐bromophenanthridine by substitution. From the 6‐carboxaldehydophenanthridine and the β‐amino‐ethylthiol, the corresponding thiazolidine or imine ...
