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

ABSTRACT: 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.

Project description:The asymmetric unit of the title compound, C(17)H(14)O(6)S, contains four crystallographically independent mol-ecules in which the pyran-one units are essentially planar, with maximum deviations of 0.016 (2), 0.019 (2), 0.025 (2), 0.014 (2), 0.020 (2), 0.010 (2), 0.003 (2) and 0.012 (2) Å. One of the thio-phene rings is disordered over two positions, with an occupancy ratio of 0.739 (4):0.261 (4).

In the crystal, mol-ecules are linked through inter-molecular O-H⋯O and C-H⋯O hydrogen bonds, forming a three-dimensional network.

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

Project description: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.

2-Hy-droxy-2-trifluoro-methyl-3,4-dihydro-2H-1-benzopyran-4-one.

Project description:The heterocyclic ring in the title compound, C(10)H(7)F(3)O(3), has a half-boat conformation with the hy-droxy-bearing C atom lying 0.595?(3)?Å out of the plane of the five remaining atoms (r.m.s. deviation = 0.022?Å) in the direction of the hy-droxy O atom. Linear supra-molecular chains along the a axis, sustained by O-H?O hydrogen bonds between the hy-droxy H and ketone O atoms, feature in the crystal packing. These chains are connected into a three-dimensional architecture by C-H?O and C-H?F contacts.

2-(2-Hy-droxy-phen-yl)-3,4-dihydro-iso-quinolin-1(2H)-one.

Project description:There are two independent mol-ecules in the asymmetric unit of the title compound, C(15)H(13)NO(2), in both the six-membered dihydro-pyridine rings adopt a half-chair conformation. The two benzene rings make dihedral angles of 43.66 (10) and 62.22 (10)° in the two mol-ecules. In the crystal, the two independent mol-ecules are linked alternately by inter-molecular O-H⋯O hydrogen bonds, forming a zigzag chain along the c axis. Furthermore, inter-molecular C-H⋯π inter-actions link the chains into a three-dimensional network.

Crystal structure of (E)-4-hy-droxy-3-{1-[(4-hy-droxy-phen-yl)imino]-eth-yl}-6-methyl-2H-pyran-2-one.

Project description:In the title Schiff base, C14H13NO4, which adopts the phenol-imine tautomeric form, the dihedral angle between the planes of the benzene and heterocyclic (r.m.s. deviation = 0.037 Å) rings is 53.31 (11)°. An intra-molecular O-H⋯N hydrogen bond closes an S(6) ring. In the crystal, mol-ecules are linked by O-H⋯O hydrogen bonds to generate C(11) chains propagating in the [010] direction. A weak C-H⋯O link is also observed, leading to the formation of R (5) 5(32) rings extending parallel to the (101) plane.

3-[5-(2,4-Dichloro-phen-yl)-1-phenyl-4,5-dihydro-1H-pyrazol-3-yl]-4-hy-droxy-2H-chromen-2-one.

Project description:In the title compound, C(24)H(16)Cl(2)N(2)O(3), the chromene ring system is almost planar, with a maximum deviation of 0.042 (1) Å. It makes dihedral angles of 3.72 (6), 73.37 (5) and 12.00 (5)° with the dihydro-pyrazole, benzene and phenyl rings, respectively. An intra-molecular O-H⋯N hydrogen bond forms an S(6) ring motif. In the crystal, mol-ecules are linked via C-H⋯O inter-actions, forming an infinite chain along the a axis. The crystal packing is further stabilized by a π-π stacking inter-action [centroid-centroid distance = 3.5471 (7) Å] and a Cl⋯Cl short contact [Cl⋯Cl = 3.214 (1) Å].

4-Hy-droxy-6-methyl-3-[3-(thio-phen-2-yl)acrylo-yl]-2H-pyran-2-one.

Project description:The title compound, C13H10O4S, crystallizes with two mol-ecules in the asymmetric unit in which the rings make dihedral angles of 3.9 (1) and 6.0 (1)°; this planarity is due in part to the presence of an intra-molecular O-H⋯O hydrogen bond, which generates an S(6) ring in each mol-ecule. Both mol-ecules represent E isomers with respect to the central C=C bond. In the crystal, mol-ecules are linked by C-H⋯O inter-actions into a three-dimensional network.

Project description:In the title mol-ecule, C(18)H(12)O(4), the phenyl ring is twisted by 23.2?(1)° from the mean plane of the chromene system. In the crystal, weak inter-molecular C-H?O hydrogen bonds link mol-ecules into zigzag chains extending in the [010] direction. An intra-molecular O-H?O hydrogen bond is also present.
