Synthesis of N-aryl substituted, five- and six-membered azacycles using aluminum-amide complexes.

Synthesis of N-aryl substituted, 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.
