  使用手性pybox配体的Cu（I）络合物催化的过酸酯催化烯烃的对映选择性烯丙基氧化。

  摘要：

  通过在室温下选择配体和perester的独特组合，可以调节催化量的Cu（I）-pybox配合物与各种过酸酯的烯烃的对映选择性烯丙基氧化，以实现高不对称诱导（最高98％ee）。温度。反应中的不对称诱导在很大程度上取决于与过酸酯的芳环相连的取代基的性质。对于高对映选择性而言，在C-5处存在宝石二苯基和在恶唑啉环的手性中心（C-4）处存在仲或叔烷基取代基是至关重要的。已提出并讨论了pi-pi堆积模型以解释反应的立体化学结果。

  日期：——

  Enantioselective allylic oxidation of olefins with various peresters, using a catalytic amount of Cu(I)-pybox complex, can be tuned to achieve high asymmetric induction (up to 98% ee) by choosing a unique combination of a ligand and a perester at room temperature. The asymmetric induction in the reaction strongly depends on the nature of the substituents attached to the aryl ring of peresters. The

  Optically active copper(II)-tris(oxazoline) complex that was synthesized as a model compound of the active site of non-heme oxygenase, was found to catalyze allylic oxidation of cycloalkenes to give the corresponding 2-cycloalkenyl benzoates with moderate to excellent enantioselectivity (up to 93% ee) under the Kharash-Sosnovsky reaction conditions.

  A tridentate tris(oxazoline) ligand (4b) was found to be an efficient chiral auxiliary for copper-mediated asymmetric allylic oxidation (Kharash-Sosnovsky reaction) of cycloalkenes. Regardless of the ring size of the substrate, the reaction examined showed good enantioselectivity higher than 81% ee. (C) 2000 Elsevier Science Ltd. All rights reserved.
• Asymmetric Kharasch Reaction:  Catalytic Enantioselective Allylic Oxidation of Olefins Using Chiral Pyridine Bis(diphenyloxazoline)−Copper Complexes and <i>tert</i>-Butyl Perbenzoate^,

  日期：1998.5.1

  Copper complexes of chiral pyridine bis(diphenyloxazoline)-type ligands have been studied as catalysts for the enantioselective allylic oxidation of olefins. Using 2.5-5 mol % of these chiral catalysts and tert-butyl perbenzoate as oxidant, optically active allylic benzoates were obtained in up to 86% ee. A variety of copper salts was studied under different conditions and in different solvents. Acetone was found to be a superior solvent for the reaction. Use of phenylhydrazine in conjunction with the chiral copper complex played a crucial role in increasing the rate of the reaction. Use of 4 Angstrom molecular sieves increased the optical yield of product in almost every case.
