  日期：2016.3.7

  An efficient reductive Claisen rearrangement, catalyzed by in situ generated copper hydride and stoichiometric in diethoxymethylsilane, has been developed. Yields of up to 95 % with good to excellent diastereoselectivities were observed in this reaction. Mechanistic studies showed that the stereospecific rearrangement proceeded via a chair transition state of (E)‐silyl ketene acetals as intermediates

  已经开发了一种有效的还原性克莱森重排反应，该反应由原位生成的氢化铜和二乙氧基甲基硅烷的化学计量组成催化。在该反应中观察到高达95％的产率，具有良好至优异的非对映选择性。机理研究表明，立体定向重排通过（E）-甲硅烷基乙烯酮缩醛作为中间产物的椅子过渡态进行，而不是通过烯醇铜进行。

  [reaction: see text]. Upon treatment with n-BuLi at low temperatures, a variety of allyl 1,1-dichlorovinyl ethers 2 undergo rearrangement to furnish gamma,delta-unsaturated esters 3 after alcohol addition. Compounds containing quaternary centers (3e: R1 = H, R2, R3 = -(CH2)5-; 3f: R1 = H, R2 = CH3, R3 = (CH2)2CH(CH3)2) may be formed in high yield and under mild conditions utilizing this protocol. The
