AB  - A heterocyclic molecule of a novel class with a multiple ring system has been synthesized using a new and simple strategy and acetic acid as catalyst. The structure of the title molecule has been determined by spectral analysis and single crystal X-ray diffraction analysis. The compound crystallizes in monoclinic system, space group P21/c, with two crystallographically independent molecules in an asymmetric unit. The two molecules show close comparable geometric parameters and a similar conformation of fused-ring systems. The crystal structure is stabilized by a combination of N–H⋅⋅⋅O and C–H⋅⋅⋅O hydrogen bonds, where independent molecules display equivalent interaction patterns.

AB  - 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.
