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.
本文描述了一种新的简单有效的方法,通过1,1,1-三氟-4-磺酰基-3-丁烯-2,2-二醇1a,b与氨基杂环的反应,制备含CF3的嘧啶并[1,2-a]苯并咪唑和吡唑并[1,5-a]嘧啶。研究了反应条件和氨基杂环性质对反应化学的影响。
