Abstract Convenient and efficientone-pot syntheses of 5-substituted-1,3,4-thiadiazol-2-ylcarbamoyl aliphatic amide acid derivatives were described and developed using sulfamic acid catalyst. Thiosemicarbazide and substituted triethylorthoester and cyclic/alicyclic anhydride were efficiently condensed using sulfamic acid to furnish 5-disubstituted-1,3,4-thiadiazol-2-ylcarbamoyl aliphatic acid and amide
