Abstract
An efficient, novel and general protocol towards the synthesis of highly functionalized ortho-amido oxobenzoxazine frameworks via ruthenium catalyzed intermolecular C-H amidation using sulfonyl azides as amidation components has been successfully developed for the first time. The salient features of this strategy are high chemo and site-selectivity, a wide range of substrate scope with excellent yields and good functional group tolerance.
