  Pd /光诱导的烷基碘化物与芳基硼酸的羰基化交叉偶联合成烷基芳基酮

  摘要：

  烷基芳基酮是通过在碘化钯/轻质条件下烷基碘化物和芳基硼​​酸的羰基交叉偶联反应合成的。在该反应中，很可能通过烷基的羰基化形成酰基铝物种，然后对芳基硼酸进行金属转移，得到相应的酰基（芳基）钯物种，准备进行还原消除以生成烷基。芳基酮。

• Synthesis of N-heterocycles, beta-amino acids, and allyl amines via aza-payne mediated reaction of ylides and hydroxy aziridines

  An ylide-based aza-Payne rearrangement of 2,3-aziridin- 1 -ols leads to an efficient process for the preparation of pyrrolidines. The aza-Payne rearrangement under the basic reaction conditions favors the formation of epoxy amines. Subsequent nucleophilic attack of the epoxide by the ylide yields a bis-anion, which upon a 5-exo-tet ring closure yields the desired pyrrolidine, thus completing the relay of the 3-membered the 5-membered nitrogen containing ring system. This process takes place with complete transfer of stereochemical fidelity, and can be applied to sterically hindered aziridinols.

  基于叶立德的2,3-氮杂环丙醇的aza-Payne重排反应导致了一种高效的吡咯烷制备过程。在碱性反应条件下进行的aza-Payne重排有利于环氧胺的形成。叶立德对环氧化物的亲核攻击产生双阴离子，随后通过5-内攻环闭合产生所需的吡咯烷，从而完成了含3-成员和5-成员氮环的环的传递。这个过程完全保持立体化学的保真度，并可应用于立体位阻的氮杂环丙醇。
