  CuCl 2催化高度立体选择性和化学选择性将炔基酰胺还原为α，β-不饱和酰胺，使用硅烷作为氢供体

  摘要：

  利用硅烷作为氢供体，开发了CuH催化的炔基酰胺的Z选择性部分还原，制得α，β-不饱和酰胺。该反应在温和的条件下进行，能够容纳广泛的炔基酰胺，包括带有末端碳-碳双键或三键的炔基酰胺，从而提供具有高立体选择性和优异收率的烯基酰胺。

• <i>Z</i>-Selective Synthesis of α,β-Unsaturated Amides with Triphenylsilylacetamides

  With the purpose of developing a method of preparing Z-alpha,beta-unsaturated amides, the Peterson reaction of the (triphenylsilyl)acetamide Ph(3)SiGH(2)COX (1, X = NBn2; 3, X = NMe2) with various aldehydes was examined. The reaction of aromatic aldehydes gave selectivities up to > 97:3. It was found that the selectivity was a function of the electronic nature of the aromatic ring and higher Z selectivity was attained with electron-rich aldehydes. With aliphatic aldehydes selectivities up to 92:8 were achieved, and unlike with analogous phosphorus reagents, less sterically hindered aldehydes gave higher Z selectivity. Also, 3, which has a smaller amide group than 1, tended to give rise to higher selectivity. A comparison with the reaction of trimethylsilyl analogues revealed the significance of the phenyl substituents on the silyl group.

  日期：——

  CuH-catalyzed Z-selective partial reduction of alkynyl amides to afford α,β-unsaturated amides using silane as the hydrogen donor is developed. This reaction is carried out under mild conditions and able to accommodate a broad scope of alkynyl amides including those bearing a terminal carbon–carbon double bond or triple bond, affording alkenyl amides with high stereoselectivity and excellent yields.
