Reactivity of Cyanogen towards N-Substituted Sulfamides: Synthesis of 1,2,5-Thiadiazole 1,1-Dioxide Derivatives

Alkorta, Ibon,Aran, Vicente J.,Davila, Elena,Ruiz, Jose R.,Stud, Manfred

, p. 1135 - 1138 (2007/10/02)

The acid-catalyzed cycloaddition of N-substituted sulfamides 1a-f with cyanogen affords 2-substituted 4-amino-2,3-dihydro-3-imino-1,2,5-thiadiazole 1,1-dioxides 5a-f which, in turn, could be easily hydrolyzed to give the corresponding 3-oxo derivatives 2a
