Preparation of 6-styrylphenanthridines

Chemistry of Heterocyclic Compounds Aims and scope

Abstract

(6-Phenanthridinylmethyl)magnesium halides do not react with aromatic and aliphatic aromatic ketones but do react with aromatic aldehydes to give the corresponding carbinols. The latter are readily dehydrated to the corresponding 6-styrylphenanthridines. 6-Cyanomethylphenanthridine reacts with aromatic aldehydes in the presence of sodium ethoxide to give 6-(α-cyanostyryl)phenanthridines and is converted to 5-acyl-6-cyanomethylene-5,6-dihydrophenanthridine on heating with acetic anhydride or benzoyl chloride.
