  Allylation with Pummerer-generated substituted vinylthionium ions

  摘要：

  Pummerer-derived substituted vinylthionium ions (allyl phenyl sulfoxide, TMSOFf, EtN(i-Pr)(2), CH2Cl2, -78 degrees C) with a beta-trimethylsilylmethyl (2), gamma-phenyl (14), or gamma-phenylthio (15) group allylate the enol silyl ethers of acetophenone (3) and cyclohexanone (4) in good yield. Allylation with (14) and (15) required slow addition of base in order to limit the rate of production of intermediate, and thus avoid unwanted sila-Pummerer type products. Hunig's base conjugate addition was not observed in these cases. Both the (E)- and (Z)- forms of allyl sulfoxide (15) were shown to equilibrate to the (E)-transoid conformer prior to allylation resulting in exclusive (E)-vinyl sulfide formation. Blocking of the gamma-position resulted in preferential alpha- attack.

  α- and γ-substituted vinylthionium ions from SnCl4 ionisation of a range of substituted 1,3- and 3,3-bis (alkyl/phenylthio) propenes allylate enol allyl ethers in good yield. Levels of regioselectivity are sterically dependent and in the case of methyl as γ-substituent may be controlled by the steric bulk of the sulfur substituent. As with the Pummerer methodology, γ-addition generally gave (E)-vinyl

  SnCl 4中的α和γ取代的乙烯基硫鎓离子一系列取代的1，3-和3，3-双（烷基/苯硫基）丙烯进行电离，可以高收率烯丙基烯醇烯丙基醚。区域选择性的水平是空间依赖性的，并且在甲基作为γ-取代基的情况下，可以通过硫取代基的空间体积来控制。与Pummerer方法一样，γ加成通常会生成（E）-乙烯基硫化物，专门暗示“游离”乙烯基硫鎓离子的中间体。在适当的情况下，可以将烯丙基化产物水解并环化为罗宾逊环化产物，脱硫为烯烃或消除为二烯。烯丙基三甲基硅烷和吲哚也以高收率被烯丙基化。具有γ-苯硫基或甲氧基的乙烯基硫鎓离子也经历反应。4。提出了机械原理。该研究以五次硝化序列结束，该序列涉及分子内捕获由该方法产生的乙烯基硫鎓离子。

  Two expedient one-pot methods have been developed for synthesis of β-aryl-β-mercaptoketones using acetophenones, benzaldehydes and thiols as starting materials. The methods involve microwave irradiation (5 min) of 1:1 mixtures of acetophenones and benzaldehydes over neutral alumina supported anhydrous potassium carbonate or amberlyst-15 in the first step, and that is followed by addition of thiol to the resulting material and keeping at room temperature for 1.5 h.

  我们开发了两种简便的一锅法合成β-芳基-β-巯基酮的工艺，使用苯乙酮、苯甲醛和硫醇作为起始原料。这两种方法包括以下步骤：首先，将苯乙酮和苯甲醛的1:1混合物在微波照射下（5分钟）与中性氧化铝负载的无水碳酸钾或安伯利斯特-15反应；然后，向所得产物中加入硫醇，并在室温下保持1.5小时。
