Methyl 2-acetamido-2-(4-hy-droxy-2-methyl-1,3-dioxo-1,2,3,4-tetra-hydro-isoquinolin-4-yl)-4-methyl-penta-noate.

ABSTRACT: In the isoquinoline ring system of the title mol-ecule, C(19)H(24)N(2)O(6), the N-heterocyclic ring is in a half-boat conformation. The mol-ecular structure is stabilized by an intra-molecular O-H?O hydrogen bond, which generates an S(7) ring motif. In the crystal, mol-ecules are linked via inter-molecular bifurcated N-H?(O,O) and weak C-H?O hydrogen bonds into a three-dimensional network.

In the isoquinoline ring system of the title mol-ecule, C(19)H(24)N(2)O(6), the N-heterocyclic ring is in a half-boat conformation. The mol-ecular structure is stabilized by an intra-molecular O-H⋯O hydrogen bond, which generates an S(7) ring motif. In the crystal, mol-ecules are linked via inter-molecular bifurcated N-H⋯(O,O) and weak C-H⋯O hydrogen bonds into a three-dimensional network. ...[more]

Crystal structure of 3-hy-droxy-methyl-1,2,3,4-tetra-hydro-isoquinolin-1-one.

Project description:In the title compound, C10H11NO2, two independent but virtually superimposable mol-ecules, A and B, comprise the asymmetric unit. The heterocyclic ring in each mol-ecule has a screw-boat conformation, and the methyl-hydroxyl group occupies a position to one side of this ring with N-C-C-O torsion angles of -55.30 (15) (mol-ecule A) and -55.94 (16)° (mol-ecule B). In the crystal, O-H⋯O and N-H⋯O hydrogen bonding leads to 11-membered {⋯HNCO⋯HO⋯HNC2O} heterosynthons, involving three different mol-ecules, which are edge-shared to generate a supra-molecular chain along the a axis. Inter-actions of the type C-H⋯O provide additional stability to the chains, and link these into a three-dimensional architecture.

Methyl 2-benzyl-4-hy-droxy-1,1-dioxo-1,2,3,4-tetra-hydro-1?,2-benzothia-zine-3-carboxyl-ate.

Project description:In the title compound, C(17)H(15)NO(5)S, the benzene ring of the fused-ring system is twisted by 11.67?(6)° with respect to the thia-zine ring. The atoms of the four-atom methyl ester group and the phenyl ring of the benzyl unit are inclined at 16.50?(7) and 44.52?(3)° with respect to the thia-zine ring. An intra-molecular O-H?O hydrogen bond gives rise to a six-membered S(6) ring motif. In the crystal, mol-ecules are extended through a C-H?O inter-action along the a axis. C-H?? inter-actions are also observed.

5-Acetyl-4-(3-hy-droxy-phen-yl)-6-methyl-1,2,3,4-tetra-hydro-pyrimidin-2-one-tris-(hy-droxy-meth-yl)ammonium chloride (2/1).

Project description:The asymmetric unit of the title compound, 2C13H14N2O3·C3H10NO3 (+)·Cl(-), contains two independent mol-ecules (A and B) of the title pyrimidine derivative and one ion-pair of tris-(hy-droxy-meth-yl)ammonium chloride. The pyrimidine ring in each pyrimidine derivative has a half-chair conformation. Its mean plane is inclined to the benzene ring by 87.2?(3)° in mol-ecule A and 85.7?(2)° in mol-ecule B. In the crystal, the pyrimidine derivatives are connected to each other by N-H?O hydrogen bonds, forming chains propagating along the b-axis direction. The chains are linked via O-H-Cl hydrogen bonds, forming corrugated sheets lying parallel to the bc plane. The sheets are linked via C-H?O hydrogen bonds, forming a three-dimensional framework. The tris-(hy-droxy-meth-yl)ammonium chloride mol-ecules are located in the cages of the framework. There are also further C-H?O hydrogen bonds and C-H?? inter-actions present in the three-dimensional framework structure. Both the cation and chloride anion of the tris-(hy-droxy-meth-yl)ammonium chloride ion pair are disordered over two positions, with a refined occupancy ratio of 0.418?(8):0.582?(8) for the cation and 0.71?(4):0.29?(4) for the anion.

Crystal structure of methyl 4-(4-hy-droxy-phen-yl)-6-methyl-2-oxo-1,2,3,4-tetra-hydro-pyrimidine-5-carboxyl-ate monohydrate.

Project description: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 pair of N-H?O hydrogen bonds. The hydroxy groups of the organic mol-ecules donate O-H?O hydrogen bonds to water mol-ecules. Further, the hy-droxy group accepts N-H?O hydrogen bonds from amides whereas the water mol-ecules donate O-H?O hydrogen bonds to the both the amide and ester carbonyl groups. Other weak inter-actions, including C-H?O, C-H?? and ?-?, further consolidate the packing, generating a three-dimensional network.
