[(1S,2S,3R,4R)-3-Hydroxy-4,7,7-trimethylbicyclo[2.2.1]heptan-2-yl]methyl[(E)-3-(trimethylsilyl)prop-2-enyl]selenonium bromide

چکیده
The title compound, a seleno-nium bromide, C(17)H(33)OSeSi(+)·Br(-), was obtained from the reaction of enanti-omerically pure 4,7,7-trimethyl-2-methyl-selanylbicyclo-[2.2.1]heptan-3-ol and (3-bromopropen-yl)trimethyl-silane in acetone. Due to the chiral bicyclic substituent, the crystal structure is not centrosymmetric and has no symmetry plane, with four chiral C atoms in the cation. The asymmetric unit contains one seleno-nium cation and one bromide anion. C-H⋯Br and O-H⋯Br hydrogen bonds link the ions, forming a one-dimensional R-helical chain-like supra-molecular structure.

The title compound C(23)H(26)O(7), was prepared by esterification of 2-ethyl-7-hydr-oxy-8-methoxy-methyl-4H-chromen-4-one with (S)-(-)-camphanic chloride. The two rings of the chromone system are coplanar, making a dihedral angle of 1.99 (19)°, and the camphanoyl unit substituted at 7-O retains the original bicyclo-[2.2.1]heptane conformation of the starting reagent.
متن کاملDuration of action of a broad range of selective κ-opioid receptor antagonists is positively correlated with c-Jun N-terminal kinase-1 activation.
The κ-opioid receptor is a widely expressed G-protein-coupled receptor that has been implicated in biological responses to pain, stress, anxiety, and depression, and its potential as a therapeutic target in these syndromes is becoming increasingly apparent. However, the prototypical selective κ-opioid antagonists have very long durations of action that have been attributed to c-Jun N-terminal k...
