The reactions of azines (isoquinolines, pyridine) with TFAA and isocyanides in a new domino process yield mesoionic acid fluorides with an imidazo[1,2-a]azine core. This multicomponent reaction has a general character, tolerating a wide range of substitution patterns on each component, and displays an unprecedented arrangement of reaction pathways. The protocol allows the incorporation of a fourth
在新的多米诺过程中,吖嗪(异喹啉、吡啶)与 TFAA 和异氰化物的反应产生具有咪唑并 [1,2-a] 嗪核心的中离子酰氟。这种多组分反应具有普遍性,可以在每个组分上容忍广泛的取代模式,并显示出前所未有的反应途径排列。该方案允许通过合适的亲核试剂(醇、硫醇、胺)与酰基氟部分的反应加入第四个合成输入。(© Wiley-VCH Verlag GmbH & Co. KGaA,69451 Weinheim,德国,2009)
