Ethyl 6-methyl-3-(2-methylprop-1-enyl)-2-oxo-4-phenyl-1,2,3,4-tetrahydropyrimidine-5-carboxylate
In the mol-ecule of the title compound, C(18)H(22)N(2)O(3), the dihydro-pyrimidinone ring adopts an envelope conformation. The dihedral angle between the phenyl ring and the mean plane through the enamine fragment is 86.04 (7)°. The mol-ecular conformation is stabilized by an intra-molecular C-H⋯O hydrogen bond. In the crystal, inter-molecular N-H⋯O hydrogen bonds link pairs of mol-ecules into ...
متن کاملEthyl 4-(5-chloro-3-methyl-1-phenyl-1H-pyrazol-4-yl)-6-methyl-2-oxo-1,2,3,4-tetrahydropyrimidine-5-carboxylate
In the title compound, C(18)H(19)ClN(4)O(3), the dihydro-pyrimidin-one ring adopts a flattened boat conformation. The dihedral angle between the phenyl and pyrazole rings is 43.39 (6)°. An intra-molecular C-H⋯O contact generates an S(8) ring motif that stabilizes the mol-ecular conformation and precludes the carbonyl O atom of the ester group from forming inter-molecular inter-actions. Mol-ecul...

The title compound, C(19)H(21)N(3)O(3)S, was synthesized via an aza-Wittig reaction of a functionalized imino-phospho-rane with phenyl isocyanate under mild conditions. In the mol-ecule, the fused thienopyrimidine ring system makes a dihedral angle of 66.30 (11)° with the phenyl ring. An intra-molecular C-H⋯O hydrogen bond occurs. The terminal -OCH(2)CH(3) group is disordered over two sites wit...
متن کاملEthyl 5-methyl-4-oxo-3-phenyl-2-propylamino-3,4-dihydrothieno[2,3-d]pyrimidine-6-carboxylate
The title compound, C(19)H(21)N(3)O(3)S, was synthesized via the aza-Wittig reaction of functionalized imino-phospho-rane with phenyl isocyanate under mild conditions. In the mol-ecule, the fused thienopyrimidine ring system is essentially planar, with a maximum deviation of 0.072 (2) Å, and makes a dihedral angle of 60.11 (9)° with the phenyl ring. An intra-molecular C-H⋯O hydrogen bond is pre...
متن کاملEthyl 4-anilino-2-methyl-5-oxo-1-phenyl-2,5-dihydro-1H-pyrrole-2-carboxylate
In the title compound, C20H20N2O3, the central 2,5-di-hydro-1H-pyrrole ring [r.m.s. deviation = 0.014 (1) Å] is oriented at dihedral angles of 77.81 (6) and 25.33 (6)°, respectively, to the attached phenyl ring and the aniline phenyl ring. An intra-molecular N-H⋯O hydrogen bond occurs. In the crystal, mol-ecules are linked through pairs of N-H⋯O hydrogen bonds, forming inversion dimers with an ...
