摘要
An original synthetic route toward dibenzo[b,e] [ 1,4]diazepin-11-ones and analogues pyridobenzodiazepinones has been developed. The method relies upon an intramolecular amination process between an (hetero)aryl halide and the appropriate aniline moiety. (C) 2004 Elsevier Ltd. All rights reserved.
