  Enantioselective α-Arylation of Carbonyls via Cu(I)-Bisoxazoline Catalysis

  摘要：

  The enantioselective alpha-arylation of both lactones and acyl oxazolidones has been accomplished using a combination of diaryliodonium salts and copper catalysis. These mild catalytic conditions provide a new strategy for the enantioselective construction and retention of enolizable alpha-carbonyl benzylic stereocenters, a valuable synthon for the production of medicinal agents.

  Stereoselective organocatalytic C−C bond formations that tolerate N‐heterocycles are valuable since these moieties are common motifs in numerous chiral bioactive compounds. Such transformations are, however, challenging since N‐heterocyclic moieties can interfere with the catalytic reaction. Here, we present a peptide that catalyzes conjugate addition reactions between aldehydes and nitroolefins bearing a

  可以耐受N杂环的立体选择性有机催化C-C键形成是有价值的，因为这些部分是许多手性生物活性化合物中的常见基序。然而，由于N-杂环部分会干扰催化反应，因此这种转化具有挑战性。在这里，我们提出了一种催化醛与硝基烯烃之间的共轭加成反应的肽，该肽具有广泛的不同N-杂环基团，具有碱性和/或H键合位点，且产率和立体选择性优异。烯胺中间体的锥体化方向的调节实现了高的立体选择性。

  Chiral framework: Chiral amines with pyrrolidine frameworks catalyze the enantioselective conjugate addition of a wide range of aldehydes to various vinyl sulfones and vinyl phosphonates in high yields and with enantioselectivities up to >99 % ee (see scheme). The high versatility of the Michael adducts is exemplified by various functionalizations with conservation of the optical purity.

  日期：2011.4.27

  The homo-Reformatsky reaction, in which a metal homoenolate of an ester is added to an aldehyde, was adapted to produce γ-lactones from unsaturated, enolizable aldehydes. By use of titanium homoenolate, 11 different γ-lactones were synthesized in one step with moderate to good yields from readily available aldehydes. In particular, this procedure allowed the rapid preparation of a series of C12 unsaturated

  均一Reformatsky反应（其中将酯的金属均烯酸酯添加到醛中）适用于从不饱和的可烯醇化的醛中生产γ-内酯。通过使用高纯钛酸钛，一步合成11种不同的γ-内酯，从容易获得的醛中获得中等至良好的收率。特别地，该方法允许快速制备一系列在双键的位置和构型上不同的C 12不饱和γ-内酯。这些参考化合物将用于鉴定黄油中以前未知的内酯。提供了合成内酯的色谱，光谱和感官描述。

  The 1,2-sulfone rearrangement resulting from nucleophilic addition to bis activated vinyl-sulfones has been studied in more detail. Various nucleophiles activated by different types of catalysts (enamine, Brönsted base, thiourea) are able to promote such rearrangement in excellent yields and moderate to excellent enantioselectivities (up to 94% ee). Mechanistic studies have led to a better understanding of the mechanism and allowed its application to other electrophiles such as vinyl-sulfone acrylates.
