Visible-light-induced dual C–C bond formation via selective C(sp3)–H bond cleavage: efficient access to alkylated oxindoles from activated alkenes and simple ethers under metal-free conditions†
Abstract
A visible-light-induced oxidative difunctionalization of activated alkenes with simple ethers via selective C(sp3)–H bond cleavage and dual C–C bond formation was developed. The reaction provides mild, efficient and atom economical access to alkylated oxindoles at room temperature under metal-free conditions.
