dihydropyrrole-functionalized phenanthridines were efficiently synthesized by the metal-free, radical cascade cyclization reaction of 2-isocyanobiphenyls with γ,δ-unsaturated oxime esters. The C–N/C–C/C–C bonds were formed via the oil bath method in a one-pot procedure with broad substrate applicability. The radical process was supported by kinetic isotope effect studies and radical inhibition studies.

An efficient, general, and convenient protocol for the synthesis of functionalized 9-amino-10-arylphenanthrene derivatives using a catalyst-free cascade reaction of arylboronic acids and 2′-cyano-biaryl-2-aldehyde N-tosylhydrazones is described. The synthesis was carried out via simple experimental conditions using Na2CO3 in 1,4-dioxane as a solvent. Moreover, the 9-amino-10-arylphenanthrene compounds

A new one-pot synthetic route to achieve the preparation of hydroxy and amine binaphthyl and biphenanthryl aryls is here reported. This approach involves the reaction of 1,4-bromoiodobenzene, 4,4′-diiodobiphenyl, and 1,4- and 1,5-diiodonaphthalene with the anions of 2-naphthylamine, 2-naphthol, and 9-phenanthrylamine under irradiation in liquid ammonia. The reactions proceed to afford triaryl derivatives
