Here we present a novel annulation of pyridinium salts with BrCF2CO2Et to access the indolizine derivatives with high efficiency. The α substitution of pyridine plays a key role in determining the reaction pathways. Various types of indolizines can be conveniently accessed from easily available pyridinium salts under mild and simple reaction conditions.
在这里,我们提出了一种新型的吡啶盐与BrCF 2 CO 2 Et的环化方法,以高效地获得吲哚嗪衍生物。吡啶的α取代在确定反应途径中起关键作用。在温和而简单的反应条件下,可以从容易获得的吡啶鎓盐中方便地获得各种类型的吲哚嗪。
