Synthesis of N-arylsubstituted, five- and six-membered azacycloalkanes, isoindolines and tetrahydroisoquinolines, has been described. In this synthesis, cyclic ethers (n = 1, 2) were treated with dimethylaluminum-amide reagents, derived from a range of aryl amines and trimethylaluminum, to afford the corresponding azacycles in good yields.

Transition metal-free electrochemical approaches for the N-cyanation of secondaryamines and the α C-cyanation of tertiaryamines have been well established, with products being obtained in moderate to good yields and with good functional group tolerance under ambient conditions. The synthetic application of the protocols has been highlighted through scale-up experiments in a galvanostatic mode. Preliminary

through the aerobic oxidation of sp3C–Hbond, providing a series of nitromethylated tetrahydroisoquinoline derivatives in high yields. The results exhibited that SbCl3, as a cheap and commercially available reagent, is an efficient initiator to promote the direct functionalization of sp3 C–Hbond with broad functional group tolerance, which is potentially applied to a wider range of C–Hbond activation
