An oxidative desymmetrization of isoindolines was realized by TBN initiated radical sp 3C-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 iso-indolines can be well tolerated. The mechanistic study shows that the C-H bond oxidation, dioxygen trapping and intramolecular 1,5-H shift might be the key steps to achieve the oxidative desymmetrization.

A cascade reaction of 3-hydroxy-2-phenylisoindolin-1-one and cyclopropyl ketone has been developed via a Br?nsted acid-promoted ring-opening/intramolecular cross-cycloaddition/[4 + 2]-cycloaddition process. The developed methodology provides straightforward access to pentacyclic isoindolin-1-one derivatives under simple reaction conditions.
