  • Rhodium-Catalyzed Asymmetric Hydrogenation of α,β-Unsaturated Carbonyl Compounds via Thiourea Hydrogen Bonding
    作者:Jialin Wen、Jun Jiang、Xumu Zhang
    DOI:10.1021/acs.orglett.6b01812
    日期:2016.9.16
    The strategy of secondary interaction enables enantioselectivity for homogeneous hydrogenation. By introducing hydrogen bonding of substrates with thiourea from the ligand, α,β-unsaturated carbonyl compounds, such as amides and esters, are hydrogenated with high enantiomeric excess. The substrate scope for this chemical transformation is broad with various substituents at the β-position. Control experiments
    二次相互作用的策略使得对映异构体能够进行均相氢化。通过引入来自配体的硫脲与底物进行氢键键合,α,β-不饱和羰基化合物(如酰胺和酯)以高对映体过量进行氢化。该化学转化的底物范围很广,在β位带有各种取代基。对照实验表明,配体ZhaoPhos的每个单元都是不可替代的。Rh / ZhaoPhos催化的不对称氢化没有观察到非线性效应。
  • A new class of readily available and conformationally rigid phosphino-oxazoline ligands for asymmetric catalysis

    日期:2005.6
    A new class of conformationally rigid phosphino-oxazoline ligands 3 were synthesized via an efficient ortho-substitution of phenyl glycinol as the key step. Divergent synthetic routes for easy ligand modulation, as well as a procedure suitable for scale-up synthesis, were established. The catalytic potential of ligands 3 has been demonstrated in the highly enantioselective Ir-catalyzed hydrogenation

    A succinct and efficient protocol was developed for the synthesis of chiral aromatic ketones via asymmetric hydrogenation of β,β-disubstituted enones with rhodium catalysts based on chiral bisphosphine thiourea ligands. A series of substrates (17 examples) was smoothly catalyzed to afford the corresponding chiral aromatic ketones in high conversions(>99%)with excellent enantioselectivities (up to 96%
