Graphical Abstract

Revitalisierung durch Sauerstoff: Eine Rhodium(III)-katalysierte Sequenz aus oxidativer C-H/N-H-Aktivierung und Anellierung eröffnet den Zugang zu substituierten 1,2-Benzothiazinen ausgehend von leicht verfügbaren NH-Sulfoximinen und Alkinen (siehe Schema; Cp*=C5Me5). Das Oxidationssystem besteht aus molekularem Sauerstoff und einer katalytischen Menge Fe(OAc)2.
