Three-substituted 4H-quinolizin-4-ones were obtained via a facile method with good selectivity and high efficiency. On the basis of alkyne substrate control, the mild and cost-efficient reaction has a broad substrate scope (20 examples, up to 93% yield) and is also easy to scale up. Active sites on the products allow for further modifications. The alkyne substrate control strategy could be further
通过简便的方法以良好的选择性和高效率获得了三取代的4 H-喹啉嗪-4-酮。在炔烃底物控制的基础上,温和且经济高效的反应具有广泛的底物范围(20个实例,产率高达93%),并且也易于扩大规模。产品上的活动站点允许进一步修改。炔烃底物的控制策略可以进一步扩展,以实现更复杂的三取代的4 H -quinolizin-4-one骨架。
