摘要：
A new simple and efficient way to CF3-containing pyrimido[1,2-a]benzimidazole and pyrazolo[1,5-a]pyrimidines, by, the reaction of 1,1,1-trifluoro-4-sulfonyl-but-3-ene-2.2-dioles 1a,b with aminoheterocycles is described. The influence of reaction conditions and nature of the aminoheterocycles on regiochemistry was investigated.
