The preparation of 5-substituted and 3,5-disubstituted isothiazoles by nucleophilic displacement reactions of the corresponding methylsulphonyl compounds
Abstract
Isothiazoles substituted in the 5-position by hydroxy-, alkoxy-, or amino-groups may be obtained by treatment of the corresponding methylsulphonyl compounds with the appropriate base. In some cases 3,5-disubstituted compounds may be prepared similarly.
