6?-Hy-droxy-5,6-dihydro-salviasperanol.

ABSTRACT: In the title compound, C(20)H(28)O(4), a diterpenoid isolated from the roots of Premna obtusifolia (Verbenaceae), the five-membered ring is in a half-chair conformation. One six-membered ring exists in a twisted-boat conformation while the other is in half-boat conformation. The crystal packing is stabilized by inter-molecular O-H?O and weak C-H?O inter-actions, generating (001) sheets.

5-Hy-droxy-7-phenyl-5-(prop-2-yn-1-yl)-5,6-dihydro-1-benzofuran-2(4H)-one monohydrate.

Project description:In the title compound, C(17)H(14)O(3)·H(2)O, the six-membered ring, which adopts a half-chair conformation, makes a dihedral angle of 24.3?(2)° with the phenyl ring. In the crystal, the components are linked by O-H?O hydrogen bonds involving the water mol-ecule, and the hy-droxy and carbonyl groups of the organic compound. These inter-actions form a square-like supra-molecular synthon unit which propagates as chains parallel to the crystallographic b axis. A C-H?O interaction also occurs.

Ethyl 5-hy-droxy-6-oxo-4-phenyl-5,6-dihydro-4H-cyclo-penta-[b]thio-phene-5-carboxyl-ate.

Project description:In the title mol-ecule, C(16)H(14)O(4)S, the dihydro-cyclo-penta-thio-phenone ring system is almost planar, with an r.m.s. deviation of 0.060?Å from the best fit plane through all nine non-H atoms. The cyclo-penta-none ring adopts a severely flattened envelope conformation with the C atom carrying the OH and ethylcarboxylate substituents at the flap. This atom lies only 0.185?(3)?Å from the plane through the other four C atoms. The phenyl substituent is inclined at 43.37?(5)° to the dihydro-cyclo-penta-thio-phenone mean plane. In the crystal, mol-ecules are linked by pairs of O-H?O hydrogen bonds, forming inversion dimers with R(2) (2)(10) ring motifs. Weak C-H?O hydrogen bonds also link mol-ecules into chains along c, while an approximately orthogonal set of C-H?O contacts form chains along b, resulting in layers lying parallel to (100). Inversion dimers also form through weaker R(2) (2)(12) C-H?S contacts, which combine with C-H?O contacts to form stacks along b.

5-Hy-droxy-6-[(E)-2-phenyl-ethen-yl]-5,6-dihydro-2H-pyran-2-one isolated from Goniothalamus ridleyi.

Project description:In the title compound, C(13)H(12)O(3), the pyran ring adopts a half-chair conformation with a C atom deviating from the least-squares plane of the remaining ring atoms by 0.606?(2)?Å. This plane and that of the benzene ring make a dihedral angle of 44.18?(6)°. In the crystal, mol-ecules are linked through O-H?O hydrogen bonds into infinite chains along the b axis, and these chains are cross-linked by C-H?O hydrogen bonded into sheets lying parallel to the bc plane. The layers are further connected via C-H?? inter-actions to form a three-dimensional supra-molecular structure.

(S,E)-3-[(2-Hy-droxy-benzyl-idene)amino]-2-(2-hy-droxy-phen-yl)-2,3-dihydro-quinazolin-4(1H)-one.

Project description:In the title compound, C(21)H(17)N(3)O(3), the dihydro-quinazoline ring adopts a screw-boat conformation and its stereogenic C atom has an S configuration. The dihedral angle between the mean planes of the two hy-droxy-phenyl rings is 86.61?(12)°. The amino H atom forms an intra-molecular hydrogen bond with a phenol O atom, while the hydrazine N atom acts as an acceptor for the H atom of the other phenol group. In the crystal, O-H?N and O-H?O hydrogen bonds and weak C-H?centroid(?-ring) inter-molecular inter-actions are observed, forming chains along [1-10] and [110].

Project description:The mol-ecule of the title compound, C11H9NO2, is essentially planar [r.m.s. deviation of the non-H atoms = 0.056?(1)?Å]. In the crystal, strong O-H?O hydrogen bonds form zigzag chains along the b axis. The mol-ecules form stacks along the a axis due to ?-? inter-actions, the shortest distance between the centroids of the benzene and pyridinone rings being 3.6146?(7)?Å.
