Ethyl 4-(furan-2-yl)-6-methyl-2-oxo-1,2,3,4-tetra-hydro-pyrimidine-5-carboxyl-ate.

ABSTRACT: The asymmetric unit of the title compound, C(12)H(14)N(2)O(4), contains two independent mol-ecules. In one independent mol-ecule, the furanyl fragment is rotationally disordered between two orientations in a 0.625?(6):0.375?(6) ratio. In the crystal, inter-molecular pyrimidine-pyrimidinone N-H?O hydrogen bonds link the mol-ecules into centrosymmetric tetra-mers, which are further associated into ribbons extending in [010] via weak inter-molecular pyrimidine-carboxyl N-H?O hydrogen bonds.

The asymmetric unit of the title compound, C(12)H(14)N(2)O(4), contains two independent mol-ecules. In one independent mol-ecule, the furanyl fragment is rotationally disordered between two orientations in a 0.625 (6):0.375 (6) ratio. In the crystal, inter-molecular pyrimidine-pyrimidinone N-H⋯O hydrogen bonds link the mol-ecules into centrosymmetric tetra-mers, which are further associated into ribbons extending in [010] via weak inter-molecular pyrimidine-carboxyl N-H⋯O hydrogen bonds. ...[more]

Ethyl 4-(4-hydroxy-phen-yl)-6-methyl-2-oxo-1,2,3,4-tetra-hydro-pyrimidine-5-carboxyl-ate monohydrate.

Project description:There are three formula units in the asymmetric unit of the title compound, C(14)H(16)N(2)O(4)·H(2)O. Mol-ecules are linked by N-H⋯O hydrogen bonds into dimers with the common R(2) (2)(8) graph-set motif. Between dimers, single N-H⋯O hydrogen bonds are formed between the other N-H group of each pyrimidine ring and the hydroxyl groups. The water mol-ecules accept O-H⋯O hydrogen bonds from the hydroxyl groups and donate hydrogen bonds to the ester groups.

Methyl 6-methoxy-carbonyl-methyl-2-oxo-4-phenyl-1,2,3,4-tetra-hydro-pyrimidine-5-carboxyl-ate.

Project description:The title compound, C(15)H(16)N(2)O(5), belongs to the class of monastrol-type anti--cancer agents and was selected for crystal structure determination in order to determine the conformational details needed for subsequent structure-activity relationship studies. The central tetra-hydro-pyrimidine ring has a flat-envelope conformation. The 4-phenyl group occupies a pseudo-axial position and is inclined at an angle of ca 90° to the mean plane of the heterocyclic ring. Of the two methyl ester groups, one (in the 5-position) is in a coplanar and the other (in the 6-position) in a perpendicular orientation with respect to the heterocyclic plane. The coplanar 5-ester group has its carbonyl bond oriented cis with respect to the pyrimidine C=C double bond. By comparison of the structural results for the present compound with those determined previously for its diethyl analogue, we have identified the mol-ecular factors which control the dual course of the Biginelli reaction with salicylaldehyde. The crystal structure is dominated by two hydrogen bonds which link the mol-ecules into chains of dimers.

Ethyl 4-(5-chloro-3-methyl-1-phenyl-1H-pyrazol-4-yl)-6-methyl-2-oxo-1,2,3,4-tetra-hydro-pyrimidine-5-carboxyl-ate.

Project description: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-ecules are linked into centrosymmetric dimers by pairs of N-H?O hydrogen bonds and the dimers are linked into infinite chains along [101] by N-H?N hydrogen bonds.

Project description:In the title compound, C(14)H(15)ClN(2)O(2)S, the tetra-hydro-pyrimidine ring adopts a twisted boat conformation with the carbonyl group in an s-trans conformation with respect to the C=C double bond of the six-membered tetra-hydro-pyrimidine ring. The mol-ecular conformation is determined by an intra-molecular C-H?? inter-action. The crystal structure is further stabilized by inter-molecular N-H?O mol-ecular chains and centrosymmetric N-H?S dimers.
