Crystal structure of ethyl 2-(4-chlorophenyl)-3-cyclopentyl-4-oxo-1-propylimidazolidine-5-carboxylate
The title compound, C20H27ClN2O3, was obtained via an original synthesis method. The central heterocyclic ring adopts a shallow envelope conformation, with the N atom bearing the cyclo-pentane ring as the flap [deviation from the other atoms = 0.442 (2) Å]. The cyclo-pentane ring adopts a twisted conformation about one of the CN-C bonds: the exocyclic C-N bond adopts an equatorial orientation. ...

In the title compound, C14H14Cl2N2O3, the chloro-phenyl ring makes a dihedral angle of 87.08 (9)° with the tetra-hydro-pyrimidine ring. There is a short intra-molecular C-H⋯O contact present. In the crystal, mol-ecules are linked via pairs of N-H⋯O hydrogen bonds, forming inversion dimers with an R (2) 2(8) ring motif. The dimers are linked via a second pair of N-H⋯O hydrogen bonds, this time e...

In the title compound, C17H21ClN2O6, the di-hydro-pyrimidine ring adopts a flattened envelope conformation, with the sp (3)-hybridized C atom forming the flap. The dihedral angle between the least-squares planes of the benzene and di-hydro-pyrimidine rings is 88.09 (6)°. An intra-molecular C-H⋯O hydrogen bond generates an S(6) ring. In the crystal, mol-ecules are linked via pairs of N-H⋯O hydro...

In the title compound, C17H22N2O6, the di-hydro-pyrimidine ring adopts a flattened boat conformation. The dihedral angle between the benzene ring and the mean plane of the di-hydro-pyrimidine ring is 75.25 (6)°. In the crystal, mol-ecules are linked via pairs of N-H⋯O hydrogen bonds, forming inversion dimers with an R 2 (2)(8) ring motif which are linked through N-H⋯O and weak C-H⋯O hydrogen bo...

In the title mol-ecule, C(21)H(19)ClO(3), the cyclo-hexene ring adopts an envelope conformation, with all substituents equatorial. The plane through its five coplanar atoms makes dihedral angles of 12.75 (14) and 74.16 (8)° with the phenyl and benzene rings, respectively. The dihedral angle between the latter two rings is 81.73 (12)°. Inter-molecular C-H⋯O hydrogen bonds and intra-molecular C-H...
