The development of conditions that allow use of inexpensive aryl chlorides as electrophiles in Pd-catalyzed alkene carboamination and carboetherification reactions is described. A catalyst composed of Pd(OAc)(2) and S-Phos minimizes N-arylation of the substrate and prevents formation of mixtures of regioisomeric products. A number of heterocycles, including pyrrolidines, isoxazolidines, tetrahydrofurans, and pyrazolidines, are efficiently generated with this method.
描述了一种条件的发展,该条件允许在 Pd 催化的烯属碳氨化和碳醚化反应中使用廉价的芳基氯作为亲电试剂。由 Pd(OAc)(2)和 S-Phos 组成的催化剂最大限度地减少了底物的 N-芳基化,并防止了区域异构产物混合物的形成。该方法可有效地生成多种杂环化合物,包括吡咯烷、异噁唑烷、四氢呋喃和吡唑烷。
