  Amide α,β-Dehydrogenation Using Allyl-Palladium Catalysis and a Hindered Monodentate Anilide

  摘要：

  A practical and direct method for the alpha,beta-dehydrogenation of amides is reported using allyl-palladium catalysis. Critical to the success of this process was the synthesis and application of a novel lithium N-cyclohexyl anilide (LiCyan). The reaction conditions tolerate a wide variety of substrates, including those with acidic heteroatom nucleophiles.

  公开号：CN104926578B

  公开（公告）日：2017-05-24

  本发明公开了一种脂肪酰胺的制备方法，属于有机化学合成技术领域。该方法以取代的末端烯烃、一氧化碳和胺缩醛或胺为原料，通过过渡金属催化剂催化或与醛共同催化，在配体参与或与添加剂共同参与下，于有机溶剂中在50‑120oC下反应12‑24小时；反应结束后抽干溶剂，柱层析即可得到脂肪酰胺类化合物。该反应原料、催化剂及添加剂廉价易得，合成工艺简单，大大降低了合成成本；反应条件温和，易于工业化；反应原料及催化剂清洁无毒，对环境污染小。

  A novel and efficient palladium‐catalyzed hydroaminocarbonylation of alkenes with aminals has been developed under mild reaction conditions, and allows the synthesis of a wide range of N‐alkyl linear amides in good yields with high regioselectivity. On the basis of this method, a cooperative catalytic system operating by the synergistic combination of palladium, paraformaldehyde, and acid was established

  在温和的反应条件下，开发了一种新颖，高效的钯与戊二烯催化的链烷烃加氢氨基羰基羰基化反应，可以以高收率和高区域选择性合成多种N-烷基线性酰胺。在此方法的基础上，建立了通过钯，多聚甲醛和酸的协同组合操作的协同催化体系，以促进烯烃与芳族和脂族胺的加氢氨基羰基化反应，而后者在常规钯催化的加氢氨基羰基化反应中反应不佳。

  The weak acid has been identified as an efficient basicity-mask to overcome the basicity barrier imparted by aliphatic amines in the Pd-catalyzed hydroaminocarbonylation, which enables both aromatic and aliphatic amines to be applicable in the palladium-catalyzed hydroaminocarbonylation reaction. Notably, by using this protocol, the marketed herbicide of Propanil and drug of Fentanyl could be easily

  弱酸已被认为是一种有效的碱性掩盖剂，可以克服脂肪族胺在Pd催化的氢氨基羰基化反应中所赋予的碱性障碍，从而使芳香族胺和脂肪族胺均适用于钯催化的氢氨基羰基化反应。值得注意的是，通过使用该方案，可以容易地以一锅的方式获得市售的丙酸的除草剂和芬太尼的药物。
