An efficient three-component, one-pot synthesis of 2-alkylthio-4-amino-5-cyano-6-aryl(alkyl)pyrimidines in water

Abstract: A convenient and practical method for the synthesis of 2-alkylthio-4-amino-5-cyano-6-aryl(alkyl)pyrimidines has been developed via a three-component, one-pot reaction from aldehydes, malononitrile and S-alkylisothiouronium salts in water at room temperature. A series of polysubstituted pyrimidines were prepared by this method in moderate to excellent yields. In addition, two kinds of pyrimidine-fused heterocyclic derivatives with potential pharmacological activity were constructed from our 2-alkylthio-4-amino-… Show more

“…Highly substituted pyrimidines were also furnished by the catalysis of SDS or triethylamine. It was noteworthy that SDS requires an additional base to facilitate the reaction while triethylamine alone [211]. Triethylamine was also studied by Yan et al [212] for the condensation reaction of amidine hydrochlorides 349 and β-bromovinyl aldehydes 350 to produce pyrimidines 351 (Scheme 100) in good to excellent yields.…”
