  (Z)-α-Haloacrylates:  An Exceptionally Stereoselective Preparation via Cr(II)-Mediated Olefination of Aldehydes with Trihaloacetates

  摘要：

  (Z)-alpha-Fluoro-, (Z)-alpha-chloro-, and (Z)-alpha-bromoacrylates were obtained with unprecedented yield and stereocontrol (>99%) via addition of the corresponding commercial trihaloacetates to aldehydes at room temperature using stoichiometric Cr(II) salts or catalytic Cr(II) with a regeneration system. The intermediate 2,2-dihalo-3-hydroxy adducts could be isolated in good yields under conditions of limited reagent at 0 degrees C.

  Finely-tuned ruthenium-catalyzed highly chemoselective and enantioselective hydrogenation of gamma-halo-gamma,delta-unsaturated-beta-keto esters at the carbonyl group was achieved under neutral reaction conditions (ee up to 97%). Both olefin and alkenyl halogen moieties, which are labile under hydrogenation conditions, remained untouched during the reaction.

  在中性反应条件下（ee高达97％），实现了钌的精细调节，催化了羰基上的gamma-卤代-gamma，δ-不饱和β-酮酸酯的高度化学选择性和对映选择性氢化。在氢化条件下不稳定的烯烃和烯基卤素部分都在反应过程中保持不变。

  A novel synthesis reaction for highly stereospecific tri- and tetra-substituted olefins is described. A single stereoisomer of stable &agr;-halo-&agr;,&bgr;-ester is produced in high yield by the reaction of aldehyde or ketone with a trihalogenated compound such as trichloroacetate in the presence of CrCl 2 in a solvent. By varying the amount of CrCl 2 used, the stable dihalohydrin intermediate may be obtained as well.

  描述了一种用于高度立体特异性三取代和四取代烯烃的新合成反应。通过醛或酮与三卤代化合物（如三氯乙酸盐）在溶剂中在CrCl2存在下的反应，可以高产率地产生稳定的α-卤代-α，β-酯的单立体异构体。通过改变使用的CrCl2量，也可以获得稳定的二卤水合物中间体。
