  A convergent method for the stereoselective synthesis of trisubstituted alkenes

  摘要：

  A method for the stereoselective, convergent synthesis of trisubstituted alkenes has been developed. The procedure features the synthesis of allylic alcohols 9 by coupling an aldehyde with a vinyl organometallic reagent. Treatment of 9 with carbon disulfide and methyl iodide gave the intermediate allylic xanthates 10 that underwent facile [3,3]-sigmatropic rearrangement to give the dithiocarbonates 11 and 12, radical reduction of which gave the (E)-alkenes 13 as the major products.

  Nonenzymatic kinetic resolution of α-aryl substituted allylic alcohols catalyzed by acyl transfer catalyst Np-PIQ

  摘要：

  Chiral alpha-aryl substituted allylic alcohols are important versatile synthetic intermediates. We report here an effective nonenzymatic kinetic resolution of racemic alpha-aryl substituted allylic alcohols by introducing different aryl groups with acyl transfer catalyst Np-PIQ and propionic anhydride, providing moderate to good selectivity factors (S=12-37).

• One-pot synthesis of α,β-epoxy ketones by palladium-catalyzed epoxidation–oxidation of terminal allylic alcohols
  作者：Fateh V. Singh、Jesus M. Pena、Hélio A. Stefani

  日期：2010.3

  herein is a one-pot synthesis of α,β-epoxy ketones using a palladium-catalyzed epoxidation–oxidation sequence. Functionalized terminal allylic alcohols are treated with m-CPBA under mild reaction conditions to obtain the α,β-epoxy ketones. The main benefit of this approach is that the epoxidation of the terminal double bond and the oxidation of the secondary alcohol occured in the same reaction under

  本文描述的是使用钯催化的环氧化-氧化顺序一锅法合成的α，β-环氧酮。官能终端烯丙基醇与处理米温和反应条件下-CPBA以获得α，β环氧酮。该方法的主要优点是，在温和的反应下，同一反应中发生了末端双键的环氧化和仲醇的氧化，并且在反应顺序中既允许了给电子功能，又吸收了吸电子功能。
• Aziridination of 2- and 3-phenyl-substituted allylic alcohols with 3-acetoxyaminoquinazolinones: probing the nature of the transition state from the diastereoselectivity of aziridination

  Aziridination of phenyl-substituted allylic alcohol 10 with 3-acetoxyaminoquinazolinone 3 (Q1NHOAc) and with 22 (Q2NHOAc) has been studied. The diastereoselectivity of these reactions is markedly changed by carrying them out in the presence of aqueous sodium hydrogen carbonate solution and under these conditions aziridinations of 10 and of its ester analogue 5 with Q2NHOAc give the same magnitude and

  已经研究了苯基取代的烯丙醇10与3-乙酰氧基氨基喹唑啉酮3（Q 1 NHOAc）和22（Q 2 NHOAc）的氮化。通过在碳酸氢钠水溶液中进行这些反应，可以显着改变这些反应的非对映选择性，并且在这些条件下，将10及其酯类似物5与Q 2 NHOAc进行叠氮化可以得到相同的幅度和非对映选择性（用Ph CO 2我）。非对映选择性的这些变化的解释是基于在存在和不存在乙酸的情况下，在用于10叠氮化的过渡态中氢键性质的差异。

  Changing places: Intramolecular B(pin)/H exchange took place in the presence of a platinum–phosphane catalyst, giving synthetically useful cis‐β‐methyl‐substituted alkenylboronates stereoselectively (see scheme; B(pin)=4,4,5,5‐tetramethyl‐1,3,2‐dioxaborolan‐2‐yl).

• Synthesis of Functionalized Epoxides by Copper-Catalyzed Alkylative Epoxidation of Allylic Alcohols with Alkyl Nitriles

  A copper-catalyzed oxyalkylation of allylic alcohols using nonactivated alkyl nitriles as reaction partners was developed. A sequence involving generation of an alkyl nitrile radical followed by its addition to a double bond and a copper-mediated formation of C(sp3)–O bond was proposed to account for the reaction outcome. The protocol provided an efficient route to functionalized tri- and tetrasubstituted

  开发了使用未活化的烷基腈作为反应伙伴的铜催化的烯丙醇的烷氧基化反应。为了说明反应的结果，提出了一个序列，该序列涉及生成烷基腈自由基，然后将其添加至双键和铜介导的C（sp 3）-O键形成。该协议通过形成具有中等至极好非对映选择性的C（sp 3）–C（sp 3）和C（sp 3）–O键，为官能化的三取代和四取代的环氧化物提供了一条有效途径。
