  钯催化的烯丙基烷基化的模块化双（恶唑啉）配体：双（恶唑啉）钯eta3-1,3-二苯基烯丙基络合物的前所未有的构象行为。

  摘要：

  高产率地制备了在各个环上具有4,5-反式（5 ag）或4,5-顺式（6 c）立体化学的新对映体双（恶唑啉）家族。他们的eta（3）-烯丙基钯配合物（8 ag，9 c和10）已被用作烯丙基烷基化反应的催化前体，对恶唑啉衍生物具有出色的对映选择性（最高96％），而Pd / 6 c体系为不活跃。对钯eta（3）-1,3-二苯基烯丙基中间体（11a，c和e）的NMR研究表明，溶液中存在syn / syn-和syn / anti-烯丙基异构体。这类似于包含衍生自丙二酸的双（恶唑啉）的Pd烯丙基络合物中eta（3）-eta（1）-eta（3）异构的第一个例子。

  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。

  stereodefined, modular amino alcohols (3-alkoxy-1-amino-1-phenyl-2-propanols), in which the steric bulk of the alkoxy and amino substituents varies smoothly, has been synthesized from enantiomerically pure phenylglycidol, prepared by Sharpless epoxidation. These amino alcohols have been evaluated as ligands in the catalyzed [(amino alcohol)(arene)RuII] transfer hydrogenation of alkyl aryl ketones,

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

  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.

  Highly modular tridentate Schiff base ligands arising from enantiopure epoxyalcohols have been prepared and evaluated in catalysis using parallel methods. The key structural motifs and experimental parameters have been identified, allowing enantioselectivities of up to 77% ee in the titatium-catalyzed trimetbylsilyl cyanide addition to aldehydes.
