Directing strategy has been extensively exploited to maintain activity and selectivity for the rapid access to functionalized molecules and pharmaceutical targets. However, ‘one‐to‐one’ activation model was usually achieved through traditional directing strategy. Herein, we achieved ‘one‐to‐two’ activation model by slight modification of simple and practical ketoxime and amide functionality. With judicious
指导策略已得到广泛利用,以保持活性和选择性,以快速获得功能化分子和药物靶标。但是,“一对一”激活模型通常是通过传统的指导策略来实现的。在这里,我们通过对简单而实用的酮肟和酰胺功能进行一些修改,实现了“一对二”激活模型。通过明智地选择导向基团,实现了Csp 3 -H和Csp 2 -H键的炔基化反应,更重要的是,实现了脱氢的Csp 3 -H炔基化,从而实现了药物在区域上的分散后期修饰。
