functionalization of allylic C–H bonds into other chemical bonds is among the most straightforward and attractive, yet challenging transformations. Herein, a transition-metal-free protocol for direct allylic C–H nitrogenation, oxygenation, and carbonation of alkenes by thianthrenation was developed. This operationally simple protocol allows for the unified allylic C–H amination, esterification, etherification
将烯丙基 C-H 键选择性官能化为其他化学键是最直接、最有吸引力但最具挑战性的转变之一。在此,开发了一种无过渡金属的方案,用于通过硫氢化对烯烃进行直接烯丙基 C-H 氮化、氧化和碳酸化。这种操作简单的协议允许统一烯丙基 C-H 胺化、酯化、醚化和乙烯基硫蒽盐的芳基化。值得注意的是,该反应以良好的收率提供了多烷基取代的烯丙基胺、铵盐、磺酰胺、酯和醚。该反应在温和条件下进行,具有优异的官能团耐受性,可用于天然产物、药物分子和多肽的后期烯丙基化,具有优异的化学选择性。
