Synthesis of novel functionalized 1,2,4-thiadiazoles from 3,4-diaminofurazane and isothiocyanates

The addition of isothiocyanates to borylated 3,4-diaminofurazane is accompanied by a rearrangement to form compounds of the 1,2,4-thiadiazole series. The derivatives of 3-(5-amino-1,2,4-thiadiazole)carboxamidoxime were prepared and it was suggested to use these reagents in heterocyclic syntheses with 1,2,4-oxadiazole or a second 1,2,4-thiadiazole ring closure.
