Efficient Syntheses of New CF3-containing Diazolopyrimidines
Abstract A new simple and efficient way to CF 3 -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 aminoheterocycl...

-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. |
