A simple and practical approach has been established for the synthesis of 6-benzylphenanthridines from benzylic hydrocarbons and 2-isocyanobiphenyls via C(sp 3)-H/C(sp 2)-H bond functionalization under metal-free condition. The reaction exhibits good functional group tolerance and delivers the target products in moderate to excellent yields. The preliminary mechanistic investigation revealed that a radical intermediate might be involved in this reaction.

An efficient and straightforward method has been developed for the synthesis of polysubstituted phenanthridines from simple aryl iodides and alkyl/aryl nitriles via the palladium-catalyzed nucleophilic addition of aryl iodides to nitriles followed by casc

A new protocol for the palladium-catalyzed free-amine-directed alkenylation of C(sp2)-H bonds and cycloamination is described. Substituted biaryl-2-amines react with various alkenes, including electron-deficient alkenes, aryl alkenes and alkyl alkenes, to give the corresponding phenanthridines with exclusive regioselectivity. The use of α-branched styrenes leads to the formation of tricyclic compounds with a seven-membered amine ring. The method operates through a free-amine-directed alkenylation and a subsequent hydroamination cyclization reaction. Seven-membered cycloamination: A new protocol for the palladium-catalyzed free-amine-directed alkenylation of C(sp2)-H bonds and subsequent cycloamination is described (see scheme). Substituted biaryl-2-amines react with various alkenes to give the corresponding phenanthridines with exclusive regioselectivity. The use of α-branched styrenes leads to the formation of tricyclic compounds with a seven-membered amine ring. Copyright
