New approach to phenanthridine alkaloids by intramolecular radical cyclization [PDF]

open access: yes, 2020
The phenanthridine core is present in several natural products namely the phenanthridine alkaloids. Their synthesis is important in the pharmaceutical industry, so the development of new synthetic methods is welcomed by them.

Studies in the reactions of N, N-Dimethyl chloramine and a variety of tri coordinate phospohorus compounds [PDF]

open access: yes, 1979
In this work the reactions "between various phosphorus (III) species and dimethyl chloramine have been studied. In all cases the phosphorous (III) species were oxidised to phosphorus (v), in most cases by ohloramination, that is by the addition of the ...

Palladium-catalyzed synthesis of pyrrole-, indole- and phenanthridine-fused polycyclic aromatic compounds from ortho-dihaloarenes [PDF]

open access: yes
Convenient palladium-catalyzed syntheses of polycyclic nitrogen heterocycles from ortho-dihaloarenes were developed. First, syntheses of pyrrole-fused derivatives via domino C-C/C-N coupling of ortho-dihaloarenes with imines were accomplished. Employment
