A facile method provides N-aryl-substituted azacycles from arylamines and cyclic ethers in the presence of POCl3 and DBU. Using this method, various azacycloalkanes, isoindolines, and tetrahydroisoquinolines were prepared in high yields. This synthetic method offers an efficient approach to the production of five- and six-membered azacycles.
