摘要

N-Substituted derivatives of 2H-1,2-benzisothiazolin-3-one l,l-dioxide possess in- teresting biological properties1- 5 and they are often used as intermediates in the synthesis of antiinflammatory drugs on the basis of the so-called oxicams6 - 8. A number of examples of the preparation of compounds of this type are described in literature, based on the alkylation of alkali salts of 2H-1,2-benzisothiazolin -3-one l,I-dioxide, either without using solvents9 - 14 or in various solvents such as aceto- ...
