Abstract

This work describes a ferrocene- and oxygen-mediated ring-opening radical recombination of benzothiazolium salts, enabling a three-component tandem reaction with anilines and benzaldehydes to rapidly build the 1,4-benzothiazin-3-one skeleton through C-S bond cleavage and sequential formation of C-O, C-N and C-S bonds.
