    摘要:
    描述了带有邻羟基烷基螯合臂的P-手性膦的立体选择性合成。合成是基于对-手性的邻-溴苯基膦(硼烷)的羟烷基化或基于它们的碳酸化反应,然后进行还原。用苯甲醛或新戊醛进行的羟烷基化提供差向异构体的混合物,该差向异构体通过色谱法分离并通过其X射线结构表征。游离P-手性邻-(羟烷基)苯基膦的初步测定,作为催化的不对称aza-MBH反应中的新功能性Lewis碱,可产生ee值高达74%的β-氨基酯衍生物。

  • P-chirogenic organocatalysts: application to the aza-Morita–Baylis–Hillman (aza-MBH) reaction of ketimines

    The P-chirogenic organocatalysts were found to promote the enantioselective aza-Morita–Baylis–Hillman reaction of ketimines derived from acyclic α-keto esters. In the P-chirogenic organocatalyzed aza-MBH reactions, α,α-disubstituted α-amino acid derivatives were obtained in high yields with high enantioselectivities (up to 97% ee).
    我们发现P-手性有机催化剂能够促进非环状α-酮酯衍生的酮亚胺的aza-Morita-Baylis-Hillman反应,实现高度的对映选择性。在P-手性有机催化的aza-MBH反应中,获得了高产率且高对映选择性的α,α-二取代α-氨基酸生物(最高可达97%对映体过量)。
  • Modular <i>P</i>-Chirogenic Phosphine-Sulfide Ligands: Clear Evidence for Both Electronic Effect and <i>P</i>-Chirality Driving Enantioselectivity in Palladium-Catalyzed Allylations

    Using the ephedrine methodology, modular stereo-selective syntheses of a new class of P-chirogenic phosphines bearing a sulfur-chelating arm (P*,S-hybrid ligand) are described. A first series of syntheses based on a Fries-like rearrangement of P-chirogenic phosphinite-boranes, which are prepared from 2-bromobenzyl or 2-bromophenethyl alcohol and are mediated by metal halide exchange, have been performed. This rearrangement affords phosphine-boranes stereospecifically with an o-hydroxy-alkylphenyl substituent. The latter residue is subsequently converted into a sulfur-containing group. In a second series, the stereoselective syntheses were achieved according to a new strategy involving a reaction of a thiophenyllithiurn reagent with a P-chirogenic phosphinite. The X-ray structures of the P*,S ligands and their palladium complexes allow us to address the absolute configuration at both the phosphorus and sulfur centers. The P*,S ligands were used in palladium-catalyzed allylic alkylations, as tests, affording asymmetric inductions up to 96% ee. Computer modeling corroborates the regio- and enantioselectivity of the Pd-catalyzed allylations and the low influence of the substituent carried by the sulfur moiety, particularly when the chelate forms a six-membered ring with the metal.
