Rhodium carbenoid mediated C-H activation of a tertiary methyl group: an enantiospecific approach to the angular triquinanes norsilphiperfolane and norcameroonanes
Journal of inorganic biochemistry, 102(1), 53-62 (2007-08-19)
In our study, we have determined the thermodynamic behavior for the replacement reaction of one and two acetyl-ligands from the diaqua-tetrakis(mu-acetylato)dirhodium(II,II) complex by purine DNA bases. The complexes were optimized at the density functional theory (DFT) level with the B3LYP
DNA cleavage by photogenerated Rh(2)(O(2)CCH(3))(4)(H(2)O)(2)(+).

This review summarizes novel stereoselective syntheses of 3,4-cis- and 3,4-trans-3-alkyl-4-silyloxycyclopentanones using a dirhodium(II)-catalyzed intramolecular C-H insertion reaction as a key reaction. Treatment of diazoketoesters (20a-e) with 1 mol % of dirhodium(II) tetraacetate gave 2,3-trans-3,4-cis-cyclopentanones (21a-e) as major products. The presence

We have previously demonstrated that hypothalmic slices obtained from adult male rats accumulate 67Cu by two ligand-dependent, saturable processes: a high and low affinity process. To further establish the generality of these uptake processes, we defined the ligand requirements and
