“…For the synthesis of related molecules, see: Braun (1923); Ahmad et al (2008); Zia-ur-Rehman et al (2005, 2009. For the biological activity of 1,2-benzothiazine 1,1-dioxides, see: Bihovsky et al (2004); Turck et al (1996); Zia-ur-Rehman et al (2006).…”

“…Owing to the verstaile applications of 1,2-benzothiazine 1,1-dioxides, considerable attention has been given to their synthesis since their very first synthesis (Braun, 1923). Among these, Piroxicam (Zia-ur-Rehman et al, 2005), and…”
