Synthesis of Stable Cyclic Sulfinamides with a Hydroperoxy Function by Oxidation of Isothiazolium Salts
摘要:
The oxidation of isothiazolium salts 4 to stable 2-aryl-2,3,4,5,6,7-hexahydro-3-hydroperoxy-1,2-benzisothiazole 1-oxides rac-cis-6 (sultims) as a new class of cyclic sulfinamides is described. The formations of the oxidation products rac-ris-6 as well as 3-hydroperoxy and 3-hydroxy sultams, 8 and 9, respectively, and isothiazol-3(2H)-one 1,1-dioxides 10 are presented.
