  摘要：

  The title compound, 6- C- glucopyranosyl- 7- O- methylapigenin dihydrate, C22H22O10 . 2H(2)O, is a natural C- glucosylflavone. The flavone skeleton is almost planar, the dihedral angle between the pyran moiety and the 4- hydroxyphenyl ring being 9.8 ( 3)degrees. The basal plane of the pyranosyl ring of the glucose moiety is almost perpendicular to the benzopyran ring system. The flavone skeletons are stacked along the a axis, forming layers parallel to ( 001). Between these hydrophobic layers, the glucose groups and water molecules of crystallization are connected via O - H ... O hydrogen bonds, forming hydrophilic layers.

  Concise synthesis of flavocommelin, 7-O-methylapigenin 6-C-, 4′-O-bis-β-d-glucoside, a component of the blue supramolecular pigment from Commelina communis

  摘要：

  Flavocommelin, 7-O-methylapigenin 6-C-, 4 '-O-bis-beta-D-glucoside, was synthesized in 9 steps from the C-glycosylation of 6-O-benzy-4-O-methylphloroacetophenone via the introduction of a cinnamoyl residue by aldol condensation and the formation of a C-ring by regioselective and oxidative ring-closure to regio-and stereoselective O-glycosylation for an overall yield of 31%.

  Flavocommelin, 6-beta-D-glucopyranosyl-2-[4-(beta-D-glu-copyranosyloxy)phenyl]-5-hydroxy-7-methoxy-4H-1-benzopyran-4-one, is a flavonoid component of a blue pigment, commelin, which is isolated from the petals of Commelina communis. The crystal structure of the octaacetate derivative, 5-hydroxy-7-methoxy-6-(3,4,5,6-tetra-O-acetyl-beta-D-glucopyranosyl)-2-[4-(3,4,5,6-tetra-O-acetyl-beta-D-glucopyranosyloxy)-phenyl]-4H-1-benzopyran-4-one, C44H48O23, has been determined by X-ray diffraction. In the crystal, the molecules are arranged parallel to each other according to the periodicity of the crystal lattice. However, intermolecular stacking of the flavanone skeletons is not observed. This suggests that the hydrophilicity of the glucose moieties is one of the important factors governing the self association.
