  The efficient intermolecular alkoxylation reactions of various enol acetates and different alcohols are developed in the electrochemical process for the first time. Enol acetates derived from either aromatic, alkyl, or alicyclic ketones, and abundant free alcohols directly used in this synthetic strategy, make this transformation very valuable in synthesis and application in the future.

  首次在电化学过程中开发了各种烯醇乙酸酯和不同醇的高效分子间烷氧基化反应。衍生自芳香族、烷基或脂环族酮的烯醇乙酸酯，以及直接用于该合成策略的丰富的游离醇，使得这种转化在未来的合成和应用中非常有价值。

• Efficient Transformation of Methyl Propargyl Ethers into α,β-Unsaturated Ketones
  作者：Yukitoshi Fukuda、Kiitiro Utimoto

  DOI：10.1246/bcsj.64.2013

  日期：1991.6

  Methyl propargyl ethers, obtained from carbonyl compounds by successive treatment with an acetylide and MeI, were easily converted to the corresponding α,β-unsaturated ketone by regioselective hydration of acetylenic moiety followed by elimination of methanol under the catalytic action of Au(III).

  通过用乙炔和 MeI 连续处理从羰基化合物中获得的甲基炔丙基醚，通过炔部分的区域选择性水合，然后在 Au(III) 的催化作用下消除甲醇，很容易转化为相应的 α,β-不饱和酮。
