  铜催化对氧碳鎓离子的对映选择性添加：异色满缩醛的炔基化

  摘要：

  我们开发了一种对映选择性、铜 (I) 催化的末端炔烃与外消旋异色满缩醛的加成。该方法是第一种对前手性氧代碳鎓离子进行对映选择性加成的过渡金属催化方法。在该反应中，TMSOTf 用于在与同时形成手性铜乙炔化物相容的条件下原位形成氧碳鎓离子。通过使用双（恶唑啉）配体，可以观察到各种富含对映体的 1-炔基异色满的良好产率和对映选择性。

  Fluoro- or Trifluoromethyl-Substituted Benzyl and Phenethyl Alcohols: Substrates for Metal-Mediated Site-Selective Functionalization

  摘要：

  It was possible to functionalize the three fluorobenzyl alcohols and the three 2-(fluorophenyl)ethanols by metalation and subsequent carboxylation, the prototype electrophilic trapping reaction. Thisopropylsilyl (TIPS) outperformed methoxymethyl (MOM) as an O-protective group making seven new fluorobenzoic acids accessible in 63% average yield. Moreover, the TIPS group tolerates weakly basic and acidic media and, therefore, may facilitate further structural eldboration. The unprotected alcohols reacted more sluggishly and were unable to provide two of the targeted products (acids 1 and 2). The yield averaged only 46% in the five other cases (acids 3-7). The direct metalation of fluorinated benzyl and phenethyl alcohols remains nevertheless an attractive option because of its operational simplicity. All three (trifluoromethyl) benzyl alcohols and two of the three (trifluoromethyl)phenethyl alcohol isomers were successfully submitted to the metalation/functionalization sequence. These five starting materials gave rise to a total of nine new benzoic acids or lactones (compounds 8-14 and 17-18). Despite the poor yields (31% on average), the organometallic methods employed are, in general, extremely selective, economical and easy to perform.

• Enantioselective Thiourea-Catalyzed Additions to Oxocarbenium Ions

  日期：2008.6.1

  Asymmetric, catalytic reactions of oxocarbenium ions are reported. Simple, chiral urea and thiourea derivatives are shown to catalyze the enantioselective substitution of silyl ketene acetals onto 1-chloroisochromans. A mechanism involving anion binding by the chiral catalyst to generate a reactive oxocarbenium ion is invoked. Catalysts bearing tertiary benzylic amide groups afforded highest enantioselectivities

  particular for the synthesis of isochromane derivatives (see scheme), are provided by the title reaction. Excellent diastereoselectivites are achieved in this reaction which proceeds through a gold‐catalyzed 1,3‐acyloxy migration. In some cases exclusively the Z isomer is detected.

  标题反应提供了新的观点，特别是对于异色烷衍生物的合成（见方案）。该反应通过金催化的1,3-酰氧基迁移而实现了出色的非对映选择性。在某些情况下，仅检测到Z异构体。
