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. ...

The title compound, C20H16ClNO3S, is built up from three fused rings, one five- and two six-membered rings, linked to a 3-eth-oxy-carbonyl group and to a 4-chloro-phenyl ring. The hydropyran ring has a flattened envelope conformation, with the C atom substituted by the 4-chloro-phenyl ring as the flap (displaced by 0.077 (2) Å from the plane through the other atoms). The fused three-ring system...
متن کاملCrystal structure of ethyl 2-amino-4-(4-methoxyphenyl)-4H-1-benzothieno[3,2-b]pyran-3-carboxylate
The mol-ecule of the title compound, C21H19NO4S, features a fused ring system whereby a five-membered ring is flanked by two six-membered rings. This is linked to an ethyl 3-carboxyl-ate group and to a meth-oxy-benzene group. The fused-ring system is quasi-planar, with the greatest deviation from the mean plane being 0.131 (1) Å for the methine C atom. The plane through the meth-oxy-benzene rin...
متن کاملCrystal structure of ethyl (4R)-2-amino-7-hydroxy-4-phenyl-4H-chromene-3-carboxylate
In the title compound, C18H17NO4, the dihedral angle between the phenyl ring and the fused six-membered ring is 77.65 (4)°. The conformation of the mol-ecule is determined in part by an intra-molecular N-H⋯O hydrogen bond between the amino H atom and the carbonyl O atom, forming an S(6) motif. In the crystal, mol-ecules are linked into N-H⋯O hydrogen-bonded inversion dimers which are then conne...
متن کاملCrystal structure of 2-amino-3-cyano-4-(4-methoxyphenyl)-4H-1-benzothieno[3,2-b]pyran
The three fused five- and six-membered rings in the title compound, C19H14N2O2S, are virtually coplanar, with the maximum deviation from the mean plane being 0.060 (1) Å. This benzothieno[3,2-b]pyran ring system is nearly perpendic-ular to the plane of the 4-meth-oxy-phenyl ring, forming a dihedral angle of 83.65 (5)°. In the crystal, mol-ecules are linked by pairs of N-H⋯N hydrogen bonds into ...
