Abstract
A catalytic asymmetric ring-closing 1,5-C-H amination of sulfamoyl azides provides chiral 1,2,5-thiadiazolidine-1,1-dioxides in up to 98% yield and up to 98% ee if the C-H bond is in a benzylic position. The reaction is catalyzed by a recently introduced simple chiral ruthenium bis(oxazoline) (pybox) complex.
