7-(Hydroxy-meth-yl)-2-(1-hydr-oxy-1-methyl-ethyl)-4-meth-oxy-2,3-dihydro-5H-furo[3,2-g]chromen-5-one methanol hemisolvate.

ABSTRACT: The title compound (cimifugin), C(16)H(18)O(6)·0.5CH(3)OH, was isolated from the rhizome of Actaea asiatica Hara. The asymmetric unit contains two independent mol-ecules and a solvent methanol mol-ecule. The five-numbered ring adopts an envelope conformation in each molecule. Intra- and inter-molecular O-H?O hydrogen bonds stabilize the crystal structure.

Project description:In the title compound, C(19)H(19)NO(2), commonly called koenimbine, the pyran ring adopts a sofa conformation. The carbazole ring system is planar [r.m.s. deviation = 0.063?(1)?Å]. A C(10) zigzag chain running along the b axis is formed through inter-molecular C-H?O hydrogen bonds. The chains are linked via weak C-H?? and N-H?? inter-actions.

Methyl [hydr-oxy(phen-yl)phosphono-meth-yl]phospho-nate methanol solvate.

Project description:The title compound, C(8)H(12)O(7)P(2)·CH(4)O, is a monoesterified bis-phospho-nate (or 1-hydroxy-methyl-ene-1,1-bis-phospho-nic acid). These synthetic compounds are widely used in medicine to inhibit bone resorption in diseases like osteoporosis, and are characterized by a stable P-C-P group and are thus analogs of inorganic pyrophosphate. By masking one or several ionizable groups, introduced as phosphono-ester, it was anti-cipated the formation of prodrugs with higher lipophilicity that could facilitate the drug delivery and metabolization. Mol-ecules are paired by inter-molecular hydrogen bonds involving the phospho-nic groups. In addition, dimers are connected side-by-side, building infinite ribbons along the a-axis direction; these ribbons are cross-linked perpendicularly along the b-axis direction via a methanol solvent mol-ecule (disordered over two sites with occupancy factors ca 0.6 and 0.4), forming an extended inter-molecular hydrogen-bonded network. The H atoms of the methyl group in the main molecule are disordered equally over two positions.

Methyl 5-(4-hy-droxy-3-meth-oxy-phen-yl)-2-(4-meth-oxy-benzyl-idene)-7-methyl-3-oxo-2,3-dihydro-5H-thia-zolo[3,2-a]pyrimidine-6-carboxyl-ate.

Project description:In the title compound, C(24)H(22)N(2)O(6)S, a pyrimidine ring substituted with 4-hy-droxy-3-meth-oxy-phenyl is fused with a thia-zole ring. The 4-hy-droxy-3-meth-oxy-phenyl group is positioned axially to the pyrimidine ring, making a dihedral angle 85.36?(7)°. The pyrimidine ring adopts a twist boat conformation. In the crystal, O-H?N inter-actions result in a chain running along the b axis. The carbonyl O atom bonded to the thia-zole ring is involved in two C-H?O hydrogen-bond inter-actions forming centrosymmetric dimers; the ten- and six-membered rings resulting from these inter-actions have R(2) (2)(10) and R(1) (2)(6) motifs, respectively.

Methyl (2Z)-2-(2-fluoro-4-meth-oxy-benzyl-idene)-5-(4-meth-oxy-phen-yl)-7-methyl-3-oxo-2,3-dihydro-5H-[1,3]thia-zolo[3,2-a]pyrimidine-6-carboxyl-ate.

Project description:The asymmetric unit of the title compound, C(24)H(21)FN(2)O(5)S, consists of two crystallographically independent mol-ecules. In each mol-ecule, the central dihydro-pyrimidine ring is significantly puckered and adopts a conformation which is best described as an inter-mediate between a boat and a screw boat. The least-squares planes of the dihydro-pyrimidine rings are almost coplanar with the fluoro-substituted benzene rings, making dihedral angles of 9.04?(7) and 6.68?(7)°, and almost perpendicular to the meth-oxy-substituted benzene rings with dihedral angles of 89.23?(7) and 88.30?(7)°. In the mol-ecular structure, S(6) ring motifs are formed by C-H?O and C-H?S hydrogen bonds. In the crystal, mol-ecules are linked into a three-dimensional network by inter-molecular C-H?O and C-H?F hydrogen bonds. The crystal structure is further stabilized by a C-H?? inter-action.
