(11R,13R)-13-(Tetra-lin-1-ylamino)-4,5-ep-oxy-11,13-dihydro-costunolide.

ABSTRACT: THE TITLE COMPOUND [SYSTEMATIC NAME: (12R)-4,8-dimethyl-12-[(1'R)-1',2',3',4'-tetrahydro-1'-naphthyl)aminomethyl]-3,14-dioxatricyclo[9.3.0.0(2,4)]tetradec-7-en-13-one}, C(25)H(33)NO(3), was formed from the reaction of (1R)-1-amino-tetra-lin with parthenolide in methano-lic solution. X-ray crystal structure analysis determined that the configuration of the new chiral center in the title compound was R.

trans-3,3',4,5'-Tetra-meth-oxy-stilbene.

Project description:The title compound, C(18)H(20)O(4), was synthesized by a Wittig-Horner reaction of diethyl 3,4-dimeth-oxy-benzyl-phosphate and 3,5-dimeth-oxy-benzaldehyde. In the crystal, the dihedral angle between the two aromatic rings is 2.47 (12)°. All the meth-oxy groups are almost coplanar with the aromatic ring to which they are attached [C-C-O-C torsion angles = -2.8 (3), -5.2 (4), -176.3 (2) and -178.0 (2)°].

Project description:The title compound, C(24)H(34)O(8), a natural ent-kaurane diterpenoid, is composed of four rings with the expected cis and trans junctions. The crystal structure is stabilized by inter-molecular O-H?O hydrogen bonds. In addition, an intra-molecular O-H?O hydrogen bond occurs.

(11R)-13-Dimethyl-ammonio-11,13-dihydro-4,5-epoxy-costunolide semifumarate.

Project description:Crystals of the title salt, C(17)H(28)NO(3) (+)·C(4)H(3)O(4) (-), were obtained by reacting parthenolide with dimethyl-amine followed by conversion of the amine adduct into a water-soluble fumarate salt. Subsequent crystallization of the fumarate salt from water afforded colorless ortho-rhom-bic crystals. The amine addition is highly stereospecific yielding exclusively a single diastereomer with R-configuration at the newly formed C-11 chiral carbon. In the crystal, intermolecular O-H?O and N-H?O hydrogen bonds help to establish the packing.
