Dimethyl 2,6-dimethyl-4-phenylpyridine-3,5-dicarboxylate
In the title compound, C(17)H(17)NO(4), the dihedral angle between the benzene and pyridine rings is 75.51 (4)°. The benzene and pyridine rings are both approximately planar (r.m.s. deviations of 0.0040 and 0.0083 Å, respectively), indicating that the pyridine N atom is not protonated. The crystal structure is stabilized by weak inter-molecular C-H⋯O and C-H⋯N inter-actions.

In the crystal of the title compound, C(11)H(15)NO(4), the mol-ecules are linked into sheets by N-H⋯O and C-H⋯O hydrogen bonds. Within the mol-ecule, the 1,4-dihydro-pyridine ring exhibits a distinctive planar conformation [r.m.s. deviation from the mean plane of 0.009 (3)Å], and the other non-H atoms are almost coplanar [r.m.s. deviation = 0.021 (3) Å] with the 1,4-dihydro-pyridine ring. The c...

متن کاملDimethyl 4-(4-ethoxyphenyl)-2,6-dimethyl-1,4-dihydropyridine-3,5-dicarboxylate
In the title mol-ecule, C(19)H(23)NO(5), the dihedral angle formed by the benzene ring and the planar part of the dihydro-pyridine ring is 83.52 (5)°. The dihydro-pyridine ring adopts a flattened boat conformation. In the crystal, mol-ecules are linked by N-H⋯O hydrogen bonds, generating chains running parallel to [100]. The crystal structure is consolidated by C-H⋯O contacts.
متن کاملDimethyl 4-(3-hydroxyphenyl)-2,6-dimethyl-1,4-dihydropyridine-3,5-dicarboxylate
The 1,4-dihydro-pyridine ring in the title compound, C(17)H(19)NO(5), has a flattened-boat conformation, and the benzene ring is almost orthogonal to it [dihedral angle = 82.98 (12)°]. The hydr-oxy group is disordered over two positions in a 0.780 (4):0.220 (4) ratio. In the crystal, hydrogen-bonding inter-actions of the type N(a)-H⋯O(c) and O(h)-H⋯O(c) (a = amine, c = carbonyl and h = hydr-oxy...
