Ethyl 7-oxo-3,5-diphenyl-1,4-diazepane-2-carboxylate
The title compound, C(20)H(22)N(2)O(3), crystallizes with two independent mol-ecules in the asymmetric unit. In both mol-ecules, the diazepane rings adopt chair conformations. The mean planes of the diazepane rings in the two molecules form dihedral angles of 71.6 (4)/40.3 (5) and 75.9 (5)/58.6 (7)° with the neighbouring benzene rings. The carbonyl-group O atoms deviate significantly from the d...

In the title compound, C(21)H(24)N(2)O(3), the diazepane ring adopts a chair conformation. The central diazepane ring forms dihedral angles 67.80 (7) and 72.29 (5)° with the two benzene rings. The eth-oxy-carbonyl group is disordered over two conformations with site-occupancy factors of 0.643 (5) and 0.357 (5). In the crystal, inversion dimers linked by pairs of N-H⋯O hydrogen bonds generate R(...

In the title compound, C13H12O5, the mean plane of the 2H-chromene ring system (r.m.s deviation = 0.026 Å) forms a dihedral angle of 81.71 (6)° with the mean plane of ethyl 2-hy-droxy-acetate moiety (r.m.s deviation = 0.034 Å). In the crystal, C-H⋯O hydrogen bonds result in the formation of zigzag layers parallel to the bc plane.

In the title compound, C(25)H(26)N(4)O(3), the two fused pyrrolo-[3,2-d]pyrimidine rings form a dihedral angle of 3.7 (2)°. The two substituent phenyl rings are twisted with respect to the pyrrole and pyrimidine rings, making dihedral angles of 57.2 (2) and 69.0 (2)°, respectively. The ethyl and eth-oxy groups are disordered over two positions; the site occupancies are 0.53 (1) and 0.47 (1) for...
متن کاملc-3,t-3-Dimethyl-r-2,c-7-diphenyl-1,4-diazepan-5-one
In the title compound, C(19)H(22)N(2)O, the diazepine ring adopts a distorted chair conformation. One of the N-H groups forms an inter-molecular N-H⋯O hydrogen bond generating an R(2) (2)(8) graph-set motif. The other N-H group does not form a hydrogen bond.
