Catalyst-free synthesis of phenanthridinesviaelectrochemical coupling of 2-isocyanobiphenyls and amines

Catalyst free synthesis of 6-aryl phenanthridines and amides through an electrochemical reaction is reported in this study. The coupling reaction proceeds by the cathodic reduction ofin situformed diazonium ions, which are formed from anilines and an alkyl nitrite. The generated aryl radical diazonium ions coupled from isocyanides furnished the desired products in good yields. This cascade reaction was conducted in an undivided cell equipped with an RVC as the anode and Pt as the cathode usingnBu4NBF4as the electrolyte at room temperature. A series of detailed mechanistic studies have also been performed, including a radical clock experiment and cyclic voltammetry analysis.

Preparation of phenanthridines from N-(o-arylbenzyl)trifluoromethanesulfonamides with 1,3-diiodo-5,5-dimethylhydantoin

Treatment of N-(o-arylbenzyl)trifluoromethanesulfonamides with 1,3-diiodo-5,5-dimethylhydantoin in 1,2-dichloroethane under irradiation with a tungsten lamp, followed by the reaction with tBuOK gave the corresponding 6-arylphenanthridines and 6-unsubstituted phenanthridines in good to moderate yields, respectively. The reaction proceeds through an oxidative cyclization onto the aromatic ring by sulfonamidyl radicals formed from the N-iodosulfonamides. The present reaction is a one-pot method for the preparation of both 6-arylphenanthridines and 6-unsubstituted phenanthridines from N-(o-arylbenzyl)trifluoromethanesulfonamides under transition-metal-free conditions.

Preparation of Phenanthridines from o-Cyanobiaryls via Addition of Organic Lithiums to Nitriles and Imino Radical Cyclization with Iodine

Simple treatment of 2-cyanobiaryls with methyllithium, ethylmagnesium bromide, butyllithium, phenyllithium, p-methylphenyllithium, etc., followed by the reaction with water and then with molecular iodine at 60 °C provided efficiently 6-methyl-, 6-ethyl-, 6-butyl-, 6-phenyl, 6-(p-methylphenyl)phenanthridines, etc., in good yields, respectively. Here, imines formed through the addition of carbanion onto the nitriles reacted with molecular iodine to form N-iodoimines smoothly, and their warming treatment induced the formation of imino radicals that smoothly cyclized onto the aryl group to give 6-alkyl- and 6-arylphenanthridines.
