- Abstract
A new three‐component strategy from aldehyde, p‐toluenesulfonyl hydrazide and potassium thiocyanate for the synthesis of 2‐aminothiadiazoles promoted by I2 under metal‐free conditions has been described. Potassium thiocyanate was used as an odorless and low‐toxicity sulfur source. A wide range of aromatic aldehydes can smoothly undergo the three‐component cyclization reaction under the optimized conditions to give the corresponding products in moderate to good yields.
