simple and effective Pd(II)-catalyzed regioselectiveC(2)–H arylation of 6,5-fused heterocycles with dioxazolones as a masked ester surrogate undermildconditions is reported. The significance of the arylation is highlighted by the new reactivity demonstrated in dioxazolones via proximal C–H activation of the cyclic carbonate of the hydroxamic acid functionalityunder protic conditions.
