Abstract
The oxidation reaction of isothiazolium salts 6 with magnesium monoperoxyphthalate (MMPP) in ethanol or water in the ultrasound bath affords new 3-hydroxysultams 10 and 3-alkoxysultams 15 in very high yields. A HPLC-API-MS(MS) method was used for monitoring of the oxidation of salts 6 with MMPP.
Key words
sultams - oxidation - magnesium monoperoxyphthalate (MMPP) - hydroperoxides
