  • Enantioselective Rh-Catalyzed Hydroboration of Silyl Enol Ethers
    作者:Wenke Dong、Xin Xu、Honghui Ma、Yaqin Lei、Zhenyang Lin、Wanxiang Zhao

    chiral boron compounds. This protocol is well suitable for activated alkenes such as vinylarenes and alkenes bearing directing groups. However, the catalytic enantioselective hydroboration of O-substituted alkenes has remained unprecedented. Here we report a Rh-catalyzed enantioselective hydroboration of silyl enol ethers (SEEs) that utilizes two new chiral phosphine ligands we developed. This approach
    烯烃的不对称硼氢化反应已被证明是合成手性硼化合物最有效的方法之一。该协议非常适用于活化的烯烃,如乙烯基芳烃和带有导向基团的烯烃。然而,O-取代烯烃的催化对映选择性硼氢化反应仍然是前所未有的。在这里,我们报告了利用我们开发的两种新手性膦配体的 Rh 催化对映选择性硼氢化硅烯醇醚 (SEE)。该方法具有反应条件温和、底物范围广、官能团耐受性好等特点,可以高效制备具有合成价值的手性硼烷醚。

    have been prepared by various synthetic methods. Rhodium(I) complexes of 3 and 8 showed high catalytic activity for hydrogenation of various kinds of prochiral ketones, which were reduced smoothly to the corresponding optically active hydroxy compounds, under hydrogen at atmospheric pressure and ambient temperature. The neutral rhodium(I) complexes (diphosphine-RhN) hydrogenated α-ketoamides and α-ketopantolactone
    两种光学活性的全烷基二膦,2,3- O-异亚丙基-2,3-二羟基-1,4-双(二烷基膦基)丁烷(Rdiop 3)和N-(N'-取代的氨基甲酰基-4-二环己基膦基-2 -dicyclohexylphosphinomethylpyrrolidine(R-Cycapp 8),已通过各种合成方法制备,3和8的铑(I)配合物对各种前手性酮的氢化显示出高催化活性,并顺利还原为相应的旋光羟基化合物在大气压和环境温度下于氢气中。中性铑(I)络合物(二膦-Rh N)以相当高的光学收率(66–77%ee)氢化α-酮酰胺和α-酮基内酯。在N-(α-酮酰基)-α-氨基酯的氢化反应中,Cydiop-Rh N催化剂与diop-Rh N体系形成明显的对比。在N-(苯乙醛基)-(S)-α-苯丙氨酸的甲酯的氢化中,通过底物的手性中心几乎没有双不对称诱导而获得72%de。
  • Chiral fully alkylated diphosphines as ligands for rhodium- and platinum-catalysed hydroformylation
    作者:Giambattista Consiglio、Franco Rama
    DOI:10.1016/0304-5102(91)85015-t
    日期:1991.5
    (R,R)-[(2,2-dimethyl-1,3-dioxolane-4,5-diyl)bis(methylene)]bis[diethylphosphine](Etdiop) and (RR)-[(2,2-dimethyl-1,3-dioxolane-4,5-diyl)bis(methylene)]bis[dicyclohexylphosphine] (Cydiop) have been used as chiral ligand in the rhodium- and in the platinum-catalyzed hydroformylations of some olefinic substrates. These ligands bring about a loss of catalytic activity with respect to the corresponding diphenylphosphine homologue, particularly in the case of the platinum systems. The regioselectivity favours the straight-chain (or less branched) isomer in the case of terminal olefins with the exception of styrene; for this substrate the rhodium-catalyzed reaction with the Etdiop ligand is completely regioselective and gives only hydratropaldehyde. The enantioselectivity is very low in all cases examined.

    Tetraalkyl analogs of DIOP, (−)-EtDIOP, (−)-i-PrDIOP, and (−)-CyDIOP, have been prepared for the first time by the reaction of (+)-2,3-O-isopropylidene-2, 3-dihydroxy-1,4-difluorobutane and the corresponding lithium dialkylphosphides. These diphosphines form cationic Rh(I) complexes, [Rh(-)-RDIOP} (NBD)]C104 (R=Et, i-Pr, and Cy), which show remarkable reactivity toward dihydrogen
