  widespread use in pharmaceutical chemistry. In particular, chiral allylic sulfones have drawn particular interest because of their synthetic utility. However, enantioselective synthesis of 1,3-disubstituted unsymmetrical chiral allylic sulfones remains a challenge. In this article, we report a protocol for (R)-DTBM-Segphos/Pd-catalyzed regio- and enantioselective hydrosulfonylation of 1,3-dienes with sulfinic

  由于其在药物化学中的广泛应用，手性砜是有机合成中的重要结构基序。特别是，手性烯丙基砜因其合成效用而引起了特别的兴趣。然而，1,3-二取代的不对称手性烯丙基砜的对映选择性合成仍然是一个挑战。在本文中，我们报告了 (R)-DTBM-Segphos/Pd 催化的 1,3-二烯与亚磺酸的区域选择性和对映选择性氢磺酰化的方案，该方案提供了原子和步骤经济的 1,3-二取代手性烯丙基砜。反应条件温和，底物范围广。结合实验和计算研究表明，反应是由配体到配体的氢转移引发的，然后是通过六元过渡态的 CS 键还原消除。发现底物的烯烃 CH 与 (R)-DTBM-Segphos 的叔丁基之间的空间排斥是对映控制的关键因素。

  We presented a method for synthesizing allylic chiral hydrazones from 1,4-disubstituted 1,3-dienes and hydrazones through a (R)-DTBM-Segphos-Pd(0)-catalyzed hydrohydrazonation reaction. This transformation has a wide range of substrates and good functional group tolerance. The desired products were obtained in medium to high yield and good regio- and enantioselectivity. Synthetic transformation of
