  FeCl 3 ·6H 2 O催化可烯化醛与缩醛的Mukaiyama-Aldol型反应

  摘要：

  衍生自可烯化醛的缩醛的Mukaiyama-aldol型缩醛与环保，低成本且稳定的催化剂FeCl 3 ·6H 2 O生成的β-甲氧基羰基化合物的收率接近定量。该方法已扩展到母体醛作为起始原料，从而导致相应的醛醇缩合物的收率较低，但效率很高。在与直链和环状甲硅烷基烯醇醚的反应中，已经测试了不同的烷基和芳基取代的缩醛和醛。反应在露天气氛中进行，不需要添加剂。在这种类型的FeCl 3 ·6H 2 O催化的缩合反应中，缩醛可以被认为是羰基部分的活化基团，而不是保护基团。

  An aldehyde-selective aerobic Wacker–Tsuji oxidation is developed. Using tert-butyl nitrite as a simple organic redox cocatalyst instead of copper or silver salts, a variety of aldehydes were achieved as major products in up to 30/1 regioselectivity as well as good to high yields at room temperature.

  醛选择性好氧Wacker-Tsuji氧化技术得到了发展。使用亚硝酸叔丁酯代替铜或银盐作为简单的有机氧化还原助催化剂，可以以高达30/1的区域选择性以及在室温下良好或高收率获得多种醛作为主要产物。

  日期：2018.9.21

  A regioselectivity switchable aerobic Wacker–Tsuji oxidation has been developed using catalytic tert-butyl nitrite as a simple organic redox cocatalyst. By solely switching the solvent, either substituted aldehydes or ketones could be prepared under mild aerobic conditions in good yields, respectively. A mechanistic explanation for the selectivity control is proposed.

  使用催化亚硝酸叔丁酯作为简单的有机氧化还原助催化剂，已经开发出了区域选择性可切换的好氧Wacker-Tsuji氧化方法。通过单独切换溶剂，可以分别在温和的需氧条件下以良好的产率制备取代的醛或酮。提出了选择性控制的机理解释。
