A photocatalytic xanthate-based radical addition/cyclization reaction cascade toward 2-biphenylisocyanides is described as a practical and modular approach to 6-alkylated phenanthridines. The use of xanthates as radical precursors allowed the synthesis of diversely 6-substituted phenanthridines. Electrophilic radicals derived from nitriles, aromatic and aliphatic ketones, malonates, and amide derivatives, as well as radicals derived from phthalimidomethyl and benzylic derivatives were successfully introduced. The reaction proceeds under mild conditions without a stoichiometric amount of oxidant. Thirty novel phenanthridine scaffolds were synthesized with yields ranging from 24 to 76%.

The invention discloses a synthetic method of 6-benzyl phenanthridine compounds. A reaction equation is as follows: formula (shown in the description), wherein R represents hydrogen, fluorine, chlorine, methyl, methoxyl or a naphthalene ring. The synthetic method has the beneficial effects that (1) the operation of the preparation process is simple and convenient, and the post-treatment of obtained products is easy; (2) high temperature and high pressure conditions are not required, and reaction conditions are mild; (3) a catalyst is not required, and the synthetic cost is lowered; (4) functional groups of a reaction substrate are high in tolerance, and the substrate is wide in range and easy to prepare; (5) an oxidant is cheap, easily available and relatively economic; (6) the reaction is efficient and high in yield; and (7) the synthetic method is pollution-free and environment-friendly.
