Rac-6-Hy-droxy-2,5,7,8-tetra-methyl-chroman-2-carboxamide from synchrotron data.

ABSTRACT: The crystal structure of the title water-soluble analogue of vitamin E, trolox amide, C(14)H(19)NO(3), solved and refined against synchrotron diffraction data, contains two mol-ecules in the asymmetric unit. In both molecules, the heterocyclic ring is in a half-chair conformation. The crystal packing features a herring-bone pattern generated by N-H?O hydrogen bonds between the hy-droxy and amide groups. O-H?O hydrogen bonds also occur.

rac-3-(4-Hy-droxy-benz-yl)chroman-4-one.

Project description:In the racemic title compound, C16H14O3, the ring of the 4-hy-droxy-benzyl substituent group forms a dihedral angle of 80.12?(12)° with the benzene ring of the chromanone system. Two C atoms of the pyran-one ring and the H atoms on the benzyl ?-C atom are disordered over two sites, with site-occupation factors of 0.818?(8) and 0.182?(8). The crystal structure is stabilized by O-H?O hydrogen bonds, which form parallel one-dimensional zigzag chains down the c axis and are inter-connected by both methine C-H?O hydrogen bonds and weak aromatic C-H?? inter-actions, giving a sheet structure lying parallel to [011].

Project description:The crystal structure of the title compound, C(14)H(17)NO(2), solved and refined against synchrotron diffraction data, contains one formula unit in an asymmetric unit. In the crystal, mol-ecules form right-handed helices located at the 2(1) screw axis parallel to the a-axis direction, generated by O-H?N hydrogen bonding between the hy-droxy group and carbonitrile group of an adjacent mol-ecule.

6-Hy-droxy-5,7,8-trimethyl-chroman-2-one.

Project description:The title compound, C(12)H(14)O(3), consists of a chromanone unit with an -OH substituent at the 4-position and methyl substituents on the remaining C atoms of the aromatic ring. The fused pyran-one ring adopts a distorted envelope conformation with the methyl-ene group adjacent to the carbonyl carbon as the flap atom. The crystal structure is stabilized by classical O-H?O hydrogen bonds and weak C-H?O and C-H?? inter-actions, generating a three-dimensional network.

Project description:In the title compound, C(14)H(15)F(3)N(2)O(5), prepared by reaction of 2-hy-droxy-benzaldehyde, ethyl 4,4,4-trifluoro-3-oxobutano-ate and urea, the tetra-pyrimidine ring adopts a half-chair conformation. The crystal structure is stabilized by five inter-molecular hydrogen bonds, three O-H⋯O and two N-H⋯O, giving cyclic dimers (through three hydrogen bonds) which are further extended into a two-dimensional network.

5-Chloro-6-hy-droxy-7,8-dimethyl-chroman-2-one.

Project description:In the title mol-ecule, C(11)H(11)ClO(3), the fused pyran ring adopts a half-chair conformation. In the crystal, inter-molecular O-H?O hydrogen bonds link mol-ecules into chains along [100]. These chains are inter-connected by weak inter-molecular C-H?O contacts which generate R(2) (2)(8) ring motifs, forming sheets parallel to (001). Tetra-gonal symmetry generates an equivalent motif along b. Furthermore, the sheets are linked along the c axis by offset ?-? stacking inter-actions involving the benzene rings of adjacent mol-ecules [with centroid-centroid distances of 3.839?(2)?Å], together with an additional weak C-H?O hydrogen bond, resulting in an overall three-dimensional network.

The crystal packing displays inter-molecular O-H?N and O-H?O hydrogen bonds in which the hy-droxy group acts as a double proton donor.
