  电化学氧化脱羧和1,2-芳基向1,2-二芳基醚合成的迁移

  摘要：

  羧酸化合物是重要的化学物质，广泛存在于各种天然产物中。它们不仅是亲核试剂，还是自由基的前体。经典的过渡金属催化和光化学脱羧在自由基化学中显示出出色的位点选择性。但是，近年来，电化学脱羧历史悠久，尚未引起足够的重视。在这项工作中，已引入3,3-二芳基丙酸的电化学氧化脱羧和1,2-芳基迁移，以与醇构建C–O键。值得注意的是，这种转变无需金属催化剂和外部氧化剂即可顺利进行。

  Organic compounds, such as precursors for aryl ethylamines such as ephedrine, aryl propylamines such as fluoxetine and propionic acid derivatives such as ibuprofen, naproxen and fenoprofen, are subjected to a yeast mediated reduction conducted in the absence of a solvent. The yeast is moistened with water and contacted with the organic compound. The yeast may then be contacted with an organic solvent to dissolve the product of the reaction into the solvent, and a solid/liquid separation used to separate the product from the yeast.
