reactions, especially those involving four or even more reagents, have been a long‐standing challenge because of the issues associated with balancing reactivity, selectivity, and compatibility. Herein, we demonstrate how the use of a reagent capsule provides straightforward access to synthetically valuable thiochromenone derivatives by a palladium‐catalyzed carbonylative four‐component reaction. To the
由于涉及平衡反应性,选择性和相容性的问题,多组分反应(尤其是涉及四种甚至更多种试剂的反应)一直是一项长期挑战。本文中,我们证明了使用试剂胶囊如何通过钯催化的羰基化四组分反应直接获得具有合成价值的硫代色酮衍生物。据我们所知,这是使用胶囊防止催化剂中毒和多组分反应不良反应的第一个例子。
