Popis: An easy access has been demonstrated for seven membered diazepines and a six membered quinoxaline. The reaction proceeds rapidly with low-cost and readily available chemicals at mild temperature and provides straight forward access to diazepines and quinoxaline. All final products are new and confirmed by spectral analysis and by single crystal X-ray analysis. Two crystal structures of the diazepines have very similar compositions, exhibit similar conformations where four condensed and coplanar rings are placed in the same orientation to the rest of molecule.
