1,2,4-Thiadiazino[3,4-b]benzothiazole: A New Cyclic Sulphenimine
摘要:
3,4-Dihydro-8-trifluoromethoxy-1,2,4-thiadiazino [3,4-b]benzothiazole (2) was prepared in five steps from 6-trifluoromethoxy-2-benzothiazolamine (riluzole, 1). The key final step consisted of an original N-S bond forming reaction between unsubstituted imine and thiol groups, using chloramine-T as reagent (75% yield).
