Abstract:

Amino pyrazole derivatives is a class of pyrazole compounds which widely used in organic synthesis for the preparation of target compounds with high biological activity and also applied in the structure of drugs.1 Various catalysts were reported for the multi component synthesis of poly substituted pyrazoles as significant medicinal heterocyclic compounds. These compounds were prepared by several catalysts such as ionic liquids,2 molecular iodine,3 piperidinium acetate 4 and Cu(OAc)2 .5 In continuation of our previous projects involving the preparation and applications of acidic ILs and solid salts in organic transformations, we have prepared and characterized a new catalyst as a N-heterocyclic sulfonic acid trichlorozincate which S-N bond formation has been formed in a six members heterocyclic compounds and it was utilized for the synthesis of polysubstituted 5‑aminopyrazole‑4‑carbonitriles which exhibits many interesting properties (Scheme 1).
