Shyshkina, Olena O. published the artcileA novel synthesis and transformations of isothiochroman 2,2-dioxide, Recommanded Product: 2-(Chloromethyl)benzonitrile, the publication is Tetrahedron Letters (2012), 53(33), 4296-4299, database is CAplus.
A convenient synthesis of isothiochromen-4-one 2,2-dioxide was carried out via cyclization of o-cyanobenzyl thioacetate by a Thorpe reaction. The reactions of isothiochromen-4-one 2,2-dioxide with nitrogen-containing nucleophilic reagents have been investigated. X-rays single crystal structures of five compounds are shown.
