Conjugated Diene-Assisted Allylic C-H Bond Activation: Cationic Rh(I)-Catalyzed Syntheses of Polysubstituted Tetrahydropyrroles, Tetrahydrofurans, and Cyclopentanes from Ene-2-Dienes

摘要

Selective C-H functionalization represents one of the most efficient and straightforward methods for accessing complex molecules from ubiquitous C-H groups. Among various C-H activation/C-C bond-forming reactions, the addition of C-H bonds across multiple bonds such as alkenes and alkynes is particularly appealing in light of atom- and step-economy considerations.
