The synthesis of sulfonated 4 H -3,1-benzoxazines via an electro-chemical radical cascade cyclization

A new route for the synthesis of sulfonated 4 H -3,1-benzoxazines has been accomplished by electrochemical radical cascade cyclizations of styrenyl amides with sulfonylhydrazines. This process demonstrates a wide substrate scope with diverse functional group compatibility under metal- and external o...

Description
Summary:A new route for the synthesis of sulfonated 4 H -3,1-benzoxazines has been accomplished by electrochemical radical cascade cyclizations of styrenyl amides with sulfonylhydrazines. This process demonstrates a wide substrate scope with diverse functional group compatibility under metal- and external oxidant-free conditions at ambient temperature.
