    Enantioselective Pd-catalysed allylation with BINOL-derived monodentate phosphite and phosphoramidite ligands
    摘要:
    P-monodentate phosphite (1) and phosphoramidite (2) ligands have been synthesised from (S)-BINOL. Complexation of the new ligands with [Rh(CO)(2)Cl](2) and [Pd(allyl)Cl](2) has been found to give neutral and cationic complexes [Rh(CO)Cl(L)](2) and [Pd(allyl)(L)(2)]+BF4-, correspondingly. Applicability of these ligands in asymmetric C*-C, C*-N, C*-S bond formation and alkene hydrogenation reactions has been demonstrated. The phosphoramidite 2 showed higher enantioselectivity than its phosphite analogue I and provided good enantio selectivity in the Pd-catalysed allylic substitution of 1,3-diphenylallyl acetate with dimethyl malonate (up to 90% ee), sodium para-toluene sulfinate (up to 75% ee), pyrrolidine (up to 65% ee) and sodium diformylamide (up to 68% ee), as well as in the Rh-catalysed hydrogenation of dimethyl itaconate (up to 76% ee).

  • PipPhos and MorfPhos:  Privileged Monodentate Phosphoramidite Ligands for Rhodium-Catalyzed Asymmetric Hydrogenation
    作者:Heiko Bernsmann、Michel van den Berg、Rob Hoen、Adriaan J. Minnaard、Gerlinde Mehler、Manfred T. Reetz、Johannes G. De Vries、Ben L. Feringa

    日期:2005.2.1
    A library of 20 monodentate phosphoramidite ligands has been prepared and applied in rhodium-catalyzed asymmetric hydrogenation. This resulted in the identification of two ligands, PipPhos and MorfPhos, that afford excellent and in several cases unprecedented enantioselectivities in the hydrogenation of N-acyldehydroamino acid esters, dimethyl itaconate, acyclic N-acylenamides, and cyclic N-acylenamides
    已制备了20个单齿亚磷酰胺配体的文库,并将其用于铑催化的不对称氢化中。这导致鉴定出两个配体,PipPhos和MorfPhos,它们在氢化N-酰基脱氢氨基酸酯,衣康酸二甲酯,无环N-酰基酰胺和环状N-酰基酰胺方面提供了极好的对空选择性,在某些情况下还具有前所未有的对映选择性。此外,提出了一种平行对映选择性测定八种酰化胺的方法。

    An unprecedented Pd-catalyzed asymmetric intramolecular cascade cyclization of aryl halides with readily available arylboronic acids proceeds through a Heck-type dearomative cyclization terminated with arylation in the presence of Pd2(dba)3 (10 mol %), Cu2O (5 mol %), and Cs2CO3 (2.0 equiv) in 1,2-dichloroethane (1.0 mL) at 100 °C for 15 h in air using BINOL-based phosphoramidite as the chiral ligand

  • Influence of Phosphoramidites in Copper-Catalyzed Conjugate Borylation Reaction
    作者:Cristina Sole、Amadeu Bonet、André H. M. de Vries、Johannes G. de Vries、Laurent Lefort、Henrik Gulyás、Elena Fernández
    DOI:10.1021/om300194k
    日期:2012.11.26
    Copper(I) has become the preferred metal to catalyze the beta-boration of alpha,beta-unsaturated carbonyl compounds, and now we demonstrate that easily accessible monodentate chiral ligands, such as phosphoramidites and phosphites, can be convenient alternative ligands to induce asymmetry in the enantioselective version of this reaction, particularly in the beta-boration of alpha,beta-unsaturated imines.

    rhodium-catalyzed asymmetric conjugate addition of potassium organotrifluoroborates to various enones in the absence of water is described. A systematic search for effective catalysts has been performed by use of high-throughput screening methods.
