P. Stanetty et Md. Mihovilovic, A synthetic approach to methyl thieno[2,3-d][1,2,3]thiadiazole carboxylates via diazotation, MONATS CHEM, 130(4), 1999, pp. 573-580
A route to methyl thieno[2,3-d][1,2,3]thiadiazole carboxylates 3 as highly
potent inducers of systemic acquired resistance (SAR) is reported. The cons
truction of the appropriately substituted thiophene precursors is elaborate
d. Cyclization towards the thiadiazole ring system was carried out using di
azotation techniques.
