Millimetre wave spectroscopy of PANHs: phenanthridine
Phys. Chem. Chem. Phys., 2007The pure rotational spectrum of phenanthridine (C(13)H(9)N), a small polycyclic aromatic nitrogen heterocycle (PANH), has been measured from 48 to 85 GHz employing Stark modulated millimetre wave absorption spectroscopy of a supersonic rotationally cold molecular beam.

Benzo[c]phenanthridine alkaloids fromCorydalis incisa
Archives of Pharmacal Research, 2000Six 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.

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 ...
