Synthesis of 2-Aryl-6H,7H-[1,3]oxazolo[5,4-d]pyrimidine-7-thione and 2-Aryl-6H,7H-[1,3]thiazolo[5,4-d]pyrimidine-7-thione Using 2-Aroylaminomalonodiamide

摘要

Oxazolo- and thiazolopyrimidines have a biological significance, since they are the structural analogs and antagonists of purine bases. Among them substances were found, which inhibit enzymes [1,2] and possess fungicidal [3] and antiviral [4] activity.
