Ethyl 5-oxo-2,3-diphenyl-cyclo-pentane-1-carboxyl-ate.

ABSTRACT: The title compound, C(20)H(20)O(3), was prepared by an acyl-oin-type condensation reaction in the presence of sodium sand and dry ether using ethyl cinnamate as the starting material. The C-O bond lengths for the carbonyl groups are 1.191?(2) and 1.198?(2)?Å, while the C-O bond in the ester group is 1.335?(2)?Å. The C-C bond lengths in the phenyl groups average 1.375?Å, while the C-C bonds in the cyclo-penta-none ring average 1.525?Å, indicating single C-C bonds in the latter.

Ethyl 7-oxo-3,5-diphenyl-1,4-diazepane-2-carboxyl-ate.

Project description: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 diazepane rings, by 0.685 (14) and 0.498 (13) Å. The eth-oxy-carbonyl groups show conformational difference between two mol-ecules, as reflected in the orientation of the carbonyl O atoms and the C-C-O-C torsion angle of -179.0 (2)° in one mol-ecule and 73.2 (2)° in the other. In one molecule there is a short N-H⋯O contact that generates an S(5) ring motif. In the crystal, N-H⋯O inter-actions generate R(2) (2)(8) graph-set motifs and C-H⋯O inter-actions generate R(2) (2)(10) and R(2) (2)(14) graph-set motifs. C-H⋯π inter-actions also occur.
