Abstract

C-H activation of arenes enables the synthesis of heterocycles via annulations between arenes and unsaturated coupling partners. Whereas nitriles fail to act as coupling partners, dioxazolones can be employed as synthons of nitriles, and subsequent coupling with arenes such as N-sulfinylimines and benzimidates bearing a functionalizable directing group provides two classes of quinazolines under Co(III)-catalysis.
