  • NEW ORTHO-FUNCTIONALIZED P-CHIRAL ARYLPHOSPHINES AND DERIVATIVES: THEIR PREPARATION AND USE IN ASYMMETRIC CATALYSIS
    申请人:Stephan Michel

    The invention relates to novel organo phosphorus P-chiral optically active compounds of formula (I) having a hydroxyl, mercapto, amino, carboxyl, sulfonyl group on aryl near a phosphorus atom, to the preparation and the use thereof in then asymmetrical catalysis of unsaturated compounds. Novel acylphosphine optically pure ligands embodied in the form of transition metal complexes exhibit an increased activity and enantloselectivity, in particular in asymmetrical hydrogenation, in comparison with the same type Uganda such as DiPAMP.

    A series of enantiopure P-stereogenic 1,2-bis[(o-RO-phenyl)(phenyl)phosphino]ethane (R-SMS-Phos) ligands wherein R= i-Pr, i-Bu, t-Bu, 3-Pen, and CH2TMS was assessed in the Rh(I)-catalyzed hydrogenation of an indicative set of olefins.

  • Impact on Hydrogenation Catalytic Cycle of the R Groups’ Cyclic Feature in “R-SMS-Phos”
    作者:Borut Zupančič、Barbara Mohar、Michel Stephan
    DOI:10.1021/ol101029s
    日期:2010.7.2
    A series of R-SMS-Phos ligands was evaluated in the Rh(I)-catalyzed hydrogenation of a set of olefins showing a marked influence of the cyclic nature and structure of the R groups. Overall, cPen- and Cy-SMS-Phos performed efficiently, while Ph- and Bn-SMS-Phos exhibited slower kinetics and furnished lower ee's also compared with C6F5CH2-SMS-Phos. The Rh(I)-(Cy-SMS-Phos) catalyst was screened under mild conditions displaying excellent enantioselectivities and high TOFs. Cases of catalysis under catalyst or substrate control were identified.
