Crystal structure of methyl 4-(4-hydroxyphenyl)-6-methyl-2-oxo-1,2,3,4-tetrahydropyrimidine-5-carboxylate monohydrate
The title hydrate, C13H14N2O4·H2O, crystallizes with two formula units in the asymmetric unit (Z' = 2). The dihedral angles between the planes of the tetra-hydro-pyrimidine ring and the 4-hy-droxy-phenyl ring and ester group are 86.78 (4) and 6.81 (6)°, respectively, for one mol-ecule and 89.35 (4) and 3.02 (4)° for the other. In the crystal, the organic mol-ecules form a dimer, linked by a pai...

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. ...

1,3-benzodioxle-4-carboxylic acid] was designed as a novel class of chiral fluorometric agents.1 The chiral agent and the analogues have been conveniently applied to enantiomer analyses of various bio-molecules using HPLC and circular dichroism.2 We recently extended the molecular design of (S)TBMB carboxylic acid to chiral nitrobenzoic acids possessing the asymmetric 1,3-benzodioxole.3 The chi...
متن کاملMethyl 4-(4-methoxyphenyl)-2-methyl-5-oxo-1,4,5,6,7,8-hexahydroquinoline-3-carboxylate
In the title compound, C(19)H(21)NO(4), the dihydro-pyridine ring adopts a distorted screw-boat conformation. The fused cyclo-hexenone ring forms a slightly distorted envelope conformation. The dihedral angle between the mean planes of the benzene and heterocyclic rings is 86.1 (7)°. An intra-molecular C-H⋯O inter-action occurs. In the crystal, mol-ecules are linked by inter-molecular N-H⋯O hyd...
متن کاملMethyl 4-(3-ethoxy-4-hydroxyphenyl)-6-methyl-2-oxo-1,2,3,4-tetrahydropyrimidine-5-carboxylate monohydrate
In the title compound, C(15)H(18)N(2)O(5)·H(2)O, the pyrimidine ring adopts a flattened-boat conformation. The eth-oxy group attached to the benzene ring is in an extended conformation. The oxopyrimidine mol-ecules are linked into centrosymmetric R(2) (2)(20) dimers by O-H⋯O hydrogen bonds. The dimers are linked by N-H⋯O hydrogen bonds, forming a two-dimensional network parallel to the bc plane...
