Abstract

A convenient and simple method of formylating 1H-isothiochromen-4(3H)-one 2,2-dioxide was carried out using dimethylformamide dimethylacetal. The reactions of 3-[(dimethylamino)methylene]-1H-isothiochromen-4(3H)-one 2,2-dioxide with nitrogen-containing nucleophilic reagents were investigated.
