The reactivity of the –C(Cl)C–CN– moiety towards an AlCl3-induced C–C bond forming reaction was investigated through the reaction of 7-chloro-5-phenyl-pyrazolo[1,5-a]pyrimidine with arenes and heteroarenes. This study furnished a novel and highly selective methodology for the preparation of 7-(hetero)aryl substituted-pyrazolopyrimidines in good to excellent yields under mild reactionconditions.
通过7-氯-5-苯基-吡唑并[1,5- a ]嘧啶的反应研究了–C(Cl)C–C N–部分对AlCl 3诱导的CC键形成反应的反应性。与芳烃和杂芳烃。这项研究提供了一种新颖且高度选择性的方法,可以在温和的反应条件下以良好的产率制备7-(杂)芳基取代的吡唑并嘧啶。
