  Development of new methods toward efficient immobilization of chiral catalysts

  摘要：

  BINOL moieties are efficiently immobilized onto the surface of a micelle-derived spherical polymer and a monolayer-protected Au cluster (Au-MPC). Ti-BINOLate complexes generated from the BINOL immobilized polymer and Au-MPC are found to promote catalytic asymmetric alkylation of benzaldehyde with Et2Zn to afford the adduct in up to 84% ee and 86% ee, respectively. Au-MPC-supported multicomponent asymmetric catalyst was prepared and used in the Michael reaction of 2-cyclohexen- 1-one with dibenzyl malonate affording the adduct in up to 67% yield and 98% ee.

  Disulfides bearing (R)-1,1'-bi-2-naphthol ((R)-BINOL) moieties at each terminal position have been successfully introduced on the surface of Au cluster. Ti-BINOLate complex generated from the obtained monolayer-protected Au cluster (MPC) promoted catalytic asymmetric alkylation of benzaldehyde with Et2Zn to afford the adduct in up to 98% yield with 86% ee. After completion of the reaction, the BINOL-functionalized MPC was easily recovered.
