acid), while for selenenyl iodide derivatives, a prevalent contribution of the Se⋯N interaction was predicted. This in silico observation has been experimentally exploited for the efficient synthesis of a small library of N-substituted benzoisoselenazol-3(2H)-ones and benzoisothiazol-3(2H)-ones considering the pharmacological relevance of ebselen recently reported also as an antiviral agent against Sars-Cov2
A variety of N-substituted l,2-benzisothiazolin-3-ones were easily synthesized from N,N'-disubstituted 2,2'-dithiodibenzamides in the presence of O-methylhydroxylamine hydrochloride. Derivatives with a primary, secondary,or tertiary alkyl group or an aryl group on the N-1 nitrogen of the l,2-benzisothiazolin-3-one were obtained.
