The Stereochemistry of Organometallic Compounds. XXIX Synthesis of Stereoidal 1,4-, 1,3- and 1,6-Diphosphines and Their Evaluation as Ligands in Metal-Catalyzed Asymmetric Synthesis

The steroidal 1,4-diphosphines 3alpha- and 3beta-diphenylphosphino-2alpha-(2′-diphenylphosphinoethyl)-5alpha-cholestanes and their 5H-benzophosphindole derivatives have been prepared and shown to be useful ligands in asymmetric hydrogenation reactions.Interestingly the 3alpha- and 3beta-derivatives lead to opposing enantioselection preferences when used in these reactions.A steroidal 1,3-diphospine, 3alpha-diphenylphosphino-2alpha-diphenylphosphinomethyl-5alpha-cholestane, has been prepared as a mixture containing some of the 3beta-epimer.The 3alpha-1,3-diphosphine led to similar enantioselection in hydrogenation reactions as the 3alpha-1,4-diphosphine, and a model is proposed to explain the sense of the enantioselectivity in the 1,4- and 1,3-diphosphines.A steroidal 1,6-diphosphine has also been prepared but leads to lower optical yields in the hydrogenation reactions.These ligands have been shown to lead to only poor to moderate optical yields when used in asymmetric carbon-carbon bond forming reactions.

Spectral investigation and structural characterization of Dibenzalacetone: beta-Cyclodextrin inclusion complex

The interaction of Dibenzalacetone (DBA) with beta-Cyclodextrin (beta-CD) producing an inclusion complex was carried out by co-precipitation method. The binding constant was determined using steady state and time-resolved fluorescence spectroscopy and the results suggested that the inclusion complex preferred 1:1 stoichiometry. The complex was characterized by UV-Visible, infrared spectroscopy (FT-IR), differential scanning calorimetry (DSC) and X-ray diffractometry (XRD). The morphological characteristics of the solid complex were analyzed by Scanning electron microscope (SEM) and Atomic force microscope (AFM). The structure of 1:1 inclusion complex of DBA with beta-CD is proposed. The Docking study reveals that this structure was found to be highly probable and energitically favorable model.

Catalyzed catalysis using carbophilic Lewis acidic gold and Lewis basic palladium: Synthesis of substituted butenolides and isocoumarins

(Figure Presented) A new strategy for gold and palladium dual-catalytic reactivity and turnover, called catalyzed catalysis, enhanced the synthetic usefulness of vinylgold intermediates by providing dual-catalytic carbon-carbon cross-coupling as an alternative to protodemetalation. This protocol enabled the synthesis of substituted butenolides and isocoumarins from allyl esters. Kinetic and spectroscopic experiments support a mechanism in which the Lewis acidic gold complex catalyzes both an initial rearrangement step and a subsequent Lewis basic palladium oxidative-addition step.

A palladium-catalyzed intermolecular vicinal diarylation of terminal 1,3-dienes using aryldiazonium tetrafluoroborates and arylboronic acids is reported. Using this technology, two different arenes are regioselectively introduced in a vicinal fashion across the terminal alkene of a variety of terminal 1,3-dienes at ambient temperature. Through the action of a chiral bicyclo[2.2.2]octadienyl ligand at -20 C, good enantioselectivity has also been achieved.
