Gold-Catalyzed [1,5]-Hydride Shift onto Unactivated Alkynes To Trigger an Intermolecular Diels–Alder Reaction
摘要:
A [1,5]-hydride shift of sp(3) C-H onto an unactivated carbon carbon triple bond catalyzed by a gold(I) complex enabled N-propargylisoindolines to be latent dienes and therefore triggered an intermolecular Diels-Alder reaction with dienophiles. This protocol provides an atom-economical and straightforward approach to access a wide range of polycyclic skeletons in high yields and with excellent diastereoselectivities from easily accessible molecules.

An oxidative desymmetrization of isoindolines was realized by TBN initiated radical sp3 C–H activation relay (CHAR), providing a series of ω-hydroxylactams in high yields. This reaction exhibits broad substrate scope and functional group tolerance, and even N-alkyl isoindolines can be well tolerated. The mechanistic study shows that the C–H bond oxidation, dioxygen trapping and intramolecular 1,5-H
