Proton-Sensitive Free-Radical Dimer Evolution Is a Critical Control Point for the Synthesis of Δ(2,2(′))-Bibenzothiazines

[Image: see text] The mechanism of the acid-dependent interring dehydrogenation in the conversion of the single-bonded 3-phenyl-2H-1,4-benzothiazine dimer 2 to the Δ(2,2(′))-bi(2H-1,4-benzothiazine) scaffold of red hair pigments is disclosed herein. Integrated chemical oxidation and oxygen consumpti...
