A convenient synthesis of isothiochromen-4-one 2,2-dioxide was carried out via cyclisation 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.
通过Thorpe反应,通过邻-氰基苄基硫代乙酸酯的环化,方便地合成了异硫氰酸-4--4-酮异1,2-二氧化物。已经研究了异硫氰酸-4--4-酮2,2-二氧化物与含氮亲核试剂的反应。
