  Functionalized S-perfluorinated sulfoximines: Preparation and evaluation in catalytic processes

  摘要：

  N-substituted S-perfluoroalkylated sulfoximines were synthesized from the NH sulfoximines either by a copper coupling reaction with aryl halides or by a reaction with electrophilic substrates. The procedure allowed the preparation of N,N'-bridged bis sulfoximines and of thioureas. The potential of these new sulfoximines was evaluated in different catalytic processes. (C) 2015 Elsevier B.V.

• Chiral CO₂-Synthons via Catalytic Asymmetric Hetero-Diels−Alder Reactions of Ketomalonate and Dienes

  A catalytic enantioselective approach for the formation of chiral CO(2)-synthons is presented. The described methodology is based on the reaction of dienes with diethyl ketomalonate using C(2)-symmetric bisoxazolines as the chiral ligands and copper(II) and zinc(II) as the Lewis acids. For cyclic dienes the reaction proceeds in good yield and with up to 93% ee for 1,3-cyclohexadiene, while for cyclopentadiene

  提出了一种手性CO（2）合成子形成催化对映选择性方法。所描述的方法是基于二烯与酮丁二酸二乙酯的反应，使用C（2）对称的双恶唑啉作为手性配体，铜（II）和锌（II）作为路易斯酸。对于环状二烯，反应以良好的收率进行，并且对于1，3-环己二烯，ee高达93％，而对于环戊二烯，该反应在低温下也进行得很好，但是升高温度会导致逆Diels-Alder反应。已经在不同条件下和针对各种二烯对反应进行了研究，并且发现对于活化的二烯，杂-Diels-Alder和Mukaiyama Aldol产物均被分离。由1的对映选择性杂Diels-Alder反应形成的化合物 3-ketolononate的3-环己二烯已转化为原理上从CO（2）和1,3-环己二烯的[2 + 4]环加成反应形成的CO（2）-合成子，以及有吸引力的光学活性1,4-二取代环己二醇。杂-Diels-Alder加合物的绝对构型是基于1,4-二取代的环己
