3-tert-Butyl 5-methyl (2R,4S,5R)-2-(4-methoxyphenyl)-4-(3-nitrophenyl)-1,3-oxazolidine-3,5-dicarboxylate
The title mol-ecule, C(23)H(26)N(2)O(8), was synthesized in three steps starting from m-nitro-cinnamic acid. The central oxazolidine ring adopts an almost perfect envelope conformation with the O atom as the flap [puckering parameter ϕ = 0.3 (6)°]. The dihedral angle formed by the benzene rings is 61.81 (9)°. In the crystal, mol-ecules are connected into double chains parallel to [010] by C-H⋯O...

In the title compound, C(18)H(19)F(3)N(2)O(7), the tetrahydropyridine ring adopts a half-chair conformation. The nitro group is disordered over two sites with occupancies of 0.780 (15) and 0.220 (15). An intra-molecular N-H⋯F hydrogen bond is observed in the mol-ecular structure. The mol-ecules are linked into a two-dimensional network parallel to (100) by O-H⋯O, N-H⋯O and C-H⋯O hydrogen bonds.

In the mol-ecule of the title compound, C(19)H(17)NO(2), the quinoline ring system is planar [maximum deviation 0.021 (3) Å] and oriented with respect to the phenyl ring at a dihedral angle of 80.44 (4)°. Intra-molecular C-H⋯O inter-actions result in the formation of five- and six-membered rings having planar and envelope conformations, respectively. In the crystal structure, inter-molecular C-...
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...

In the title compound, C(19)H(16)ClNO(2), the quinoline ring system is planar (r.m.s. deviation = 0.008 Å). The phenyl group and the -CO(2) fragment of the ester unit form dihedral angles of 60.0 (1) and 60.5 (1)°, respectively, with the quinoline ring system.
