Ruthenium catalyzed chemo and site-selective C-H amidation of oxobenzoxazine derivatives with sulfonyl azides

Bakthadoss, Manickam,Kumar, Polu Vijay,Kumar, Ravan,Surendar, Manickam,Sharada, Duddu S.

supporting information, p. 14190 - 14195 (2019/09/18)

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.
