paper describes a method for the palladium catalyzed intramolecular C–H arylation using tosylates and mesylates as electrophiles. The transformation is efficient for the synthesis of various heterocyclic motifs including furans, carbazoles, indoles, and lactams. Additionally, a protocol for the one-pot sequential tosylation/arylation of phenol derivatives is presented.
本文介绍了一种使用甲苯磺酸盐和甲磺酸盐作为亲电子试剂进行钯催化的分子内CH-H芳基化的方法。该转化对于合成各种杂环基序有效,包括呋喃,咔唑,吲哚和内酰胺。另外,提出了一种用于苯酚衍生物的一锅顺序甲苯磺酸化/芳基化的方案。
