- 中文摘要: The pyrazolo[1,5-a]pyrimidines 4, 10, 11 and 14 were synthesized from reaction of 4-aryazo-2,5-diaminopyrazoles 1 with cyclic b-ketoesters 2a,b or cyclic b-ketoesters 7, 8 or acetoacetanilide 12, respectively. The reaction of 1 with the enamines 15, 16 and 17 yielded also the pyrazolo[1,5-a]pyrimidines 18, 20 and 21, respectively.
