  A New Family of Modular Chiral Ligands for the Catalytic Enantioselective Reduction of Prochiral Ketones

  摘要：

  A family of enantiomerically pure (4R,5R)-2-alkyl-4-phenyl-5-(R-oxymethyl) 1,3,2-oxazaborolidines (5) [boron substituent: H, CH3, n-C4H9; R-oxy group: CH3O, CH3OCH2CH2O, CH3(OCH2CH2)(2)O, PhCH2O, Ph2CHO, Ph3CO] has been prepared from (2S,3S)-2,3-epoxy-3-phenylpropanol (2) through a four-step sequence involving protection of the alcohol, regioselective ring-opening of the epoxide with sodium azide in acetonitrile in the presence of LiClO4, reduction of the azido group (H-2/PdC/MeOH or NaBH4/THF-MeOH), and formation of the oxazaborolidine ring with the appropriate boron reagent. Both the boron substituent and the R-oxy group have been optimized for maximal enantioselectivity in the reduction of prochiral ketones with borane. The optimal oxazaborolidine (5a-Me) [boron substituent: CH3; R-oxy group: CH3O] has been employed (10% molar amount, THF, 0 degrees C to room temperature) in the reduction of a representative family of 10 substrates comprising alkyl aryl ketones and dialkyl ketones. In these reductions, Ba-Rie induces the formation of secondary alcohols of S configuration with high enantioselectivity (93% mean enantiomeric excess). The origin of the enantioselectivity in the reduction has been rationalized by means of semiempirical AM1 calculations.

  palladium complexes have been used as chiral mediators in the asymmetric allylic alkylation reaction. The oxazoline moiety in 12 contains a C-4 aryl and a C-5 alkoxymethyl substituent that can be independently optimized for high catalytic activity and enantioselectivity. A methoxymethyl substituent at C-5 has been found to provide the best results in terms of enantioselectivity and activity in the alkylation

  制备了由对映体纯的β-氨基醇衍生而来的手性膦恶唑啉系列（12a–e），其钯配合物已用作不对称烯丙基烷基化反应中的手性介体。12中的恶唑啉部分含有一个C-4芳基和一个C-5烷氧基甲基取代基，可以针对高催化活性和对映选择性进行独立优化。在热和微波辅助活化下，已发现在C-5处的甲氧基甲基取代基在对映选择性和在多种烯丙基底物家族的烷基化中的活性方面提供了最佳结果。这项工作中描述的钯-膦基恶唑啉配合物非常坚固，因为不对称烯丙基烷基化反应中记录的对映选择性在20至130°C的温度范围内基本保持不变。在1，3-二苯基烯丙基和1，3-二甲基烯丙基烷基化底物之间观察到前所未有的对映选择性逆转，并且已经通过ONIOM QM / MM计算解释了这种行为的起因。
