9-Hy-droxy-4,8-dimethyl-12-(piperidin-1-ylmeth-yl)-3,14-dioxatricyclo-[9.3.0.0]tetra-dec-7-en-13-one.

ABSTRACT: The title compound, C(20)H(31)NO(4), was synthesized from 9?-hy-droxy-parthenolide (9?-hy-droxy-4,8-dimethyl-12-methylen-3,14-dioxa-tricyclo-[9.3.0.0(2,4)]tetra-dec-7-en-13-one), which was isolated from the chloro-form extract of the aerial parts of Anvillea radiata. The mol-ecule is built up from fused five-and ten-membered rings with the pipyridin-1-yl-methyl group as a substituent. The ten-membered ring adopts an approximate chair-chair conformation, while the six-membered ring display a chair conformation and the five-membered ring an envelope conformation with the C(H)-C-C(H) atom at the flap. The dihedral angle between the ten-membered ring and the lactone ring is 21.7?(4)°. The mol-ecular conformation is stabilized by an O-H?N hydrogen bond and the crystal structure is stabilized by weak inter-molecular C-H?O inter-actions.

3-Hy-droxy-1-(4-meth-oxy-benz-yl)piperidin-2-one.

Project description:The title compound, C13H17NO3, adopts a conformation in which the aromatic ring and the mean plane of the piperidine ring are almost perpendicular to each other [dihedral angle = 79.25?(6)°]. The presence of the carbonyl group alters the conformation of the piperidine ring from a chair to a twisted half-chair conformation. In the crystal, pairs of strong O-H?O hydrogen bonds link the mol-ecules into inversion dimers. Weak C-H?O inter-actions extend the hydrogen-bonding network into three dimensions.

4-{[4-(Hy-droxy-meth-yl)piperidin-1-yl]meth-yl}phenol.

Project description:In the title compound, C(13)H(19)NO(2), the piperidine ring has a chair conformation with the exocyclic N-C bond in an equatorial position. In the crystal, mol-ecules are linked head-to-tail by phenol O-H⋯O hydrogen bonds to hy-droxy-methyl-ene O-atom acceptors, forming chains which extend along [100]. These chains form two-dimensional networks lying parallel to (101) through cyclic hydrogen-bonding associations [graph set R(4) (4)(30)], involving hy-droxy O-H donors and piperidine N-atom acceptors.
