Synthesis and crystal structure of methyl 3-(3-hy-droxy-3-phenyl-prop-2-eno-yl)benzoate.

The title compound, CHO, was synthesized under mild conditions and characterized by various analytical techniques. Combined NMR and X-ray diffraction data show that the substance exists exclusively in the enol tautomeric form. An intra-molecular ⋯O=C-C=C-OH⋯ hydrogen bond is present in the mol-ecular structure.

Crystal structure of an unknown solvate of dodecakis-(μ2-alaninato-1:2κ(2) O:N,O)cerium(III)hexa-nickel(II) aqua-tris-(hydroxido-κO)tris-(nitrato-κ(2) O,O')cerate(III).

The chiral title compound, [CeNi6(C3H6NO2)12][Ce(NO3)3(OH)3(H2O)], comprises a complex heterometallic Ni/Ce cation and a homonuclear Ce anion. Both the cation and anion exhibit point group symmetry 3. with the Ce(III) atom situated on the threefold rotation axis.

Secondary structure-stretched forms of long intron RNA products from the view point of initiation of chromosome homologs somatic pairing.

In different types of chromosome pairing (meiotic, somatic, and sister chromatids pairing) initiation stages are less elucidated. In somatic homolog pairing initiation, the long intron RNA products interference may play the essential role. The strongest somatic pairing in Drosophila melanogaster 28B1-B2 locus and its enrichment by long bi-directional transcripts prone us to analyze the pre-mRNA secondary structures.
