  摘要：

  通过N-甲苯磺胺类与酰基重氮甲烷的亲核缩合制备了一系列β-（N-甲苯磺酰基）氨基重氮羰基化合物。这些重氮羰基化合物在各种催化条件下的重氮分解，包括羧酸Rh（II），Cu（I）和Cu（II）配合物，PhCO（2）Ag / Et（3）N，TsOH和SnCl（2） .2H（2）O，已被调查。发现在大多数情况下，重氮分解优先产生1,2-芳基迁移产物，但当PhCO（2）Ag / Et（3）N是催化体系时，1,2-氢化物迁移占主导。Hammett相关性已用于分析1，2-芳基迁移的电子效应。讨论了控制迁移偏好和反应机理的因素。

  摘要：

  允许将亲核试剂和亲电试剂添加到重氮化合物上的对映选择性催化方法可以快速进入重要的构建模块。在此，我们报告了使用乙炔基苯并氧醇-(on)e 试剂和简单的铜双恶唑啉催化剂对重氮化合物进行高度对映选择性的氧炔基化反应。获得的α-苯甲酰氧基炔丙酯是有用的结构单元，使用其他方法难以以对映体纯形式合成。所得产物可以有效地转化为邻二醇和α-羟基炔丙酯而不会损失对映体纯度。

  The intramolecular [4+2] cycloaddition between arenes and allenes first reported by Himbert gives rapid access to rigid polycyclic scaffolds. Herein, we report a one‐pot oxyalkynylation/cycloaddition reaction proceeding under mild conditions (23–90 °C) and providing complex polycyclic architectures with high efficiency, and atom and step economy. The bicyclo[2.2.2]octadiene products were obtained with
