Abstract

A methodology for the γ-butyrolactam scaffolds via ligand-enabled C(sp³)–H bond functionalization of sulfonamides with olefins has been demonstrated. The protocol has been found to be compatible with several activated and unactivated olefins, and the desired lactams were formed in excellent yields. A plausible mechanism has been described to account for the desired lactamization reaction as well as supported by mechanistic investigation including a ¹H NMR study and isolation of a palladacycle intermediate.

期刊介绍： Organic Letters invites original reports of fundamental research in all branches of the theory and practice of organic, physical organic, organometallic,medicinal, and bioorganic chemistry. Organic Letters provides rapid disclosure of the key elements of significant studies that are of interest to a large portion of the organic community. In selecting manuscripts for publication, the Editors place emphasis on the originality, quality and wide interest of the work. Authors should provide enough background information to place the new disclosure in context and to justify the rapid publication format. Back-to-back Letters will be considered. Full details should be reserved for an Article, which should appear in due course.
