An efficient NaBArF4‐catalyzed oxidative cyclization of readily available 1,5‐ and 1,6‐diynes has been developed. Importantly, this transition metal‐free oxidative catalysis proceeds via a presumable Lewis acid‐catalyzed SN2’ pathway, which is distinct from the relevant oxidative rhodium and gold catalysis. This method leads to the facile and practical construction of a diverse range of synthetically
已经开发出一种高效的NaBAr F 4催化氧化环化反应,该反应可轻松获得1,5和1,6二炔。重要的是,这种无过渡金属的氧化催化是通过一种可能的路易斯酸催化的S N 2'途径进行的,这与相关的氧化铑和金的催化作用不同。这种方法可以轻松实用地构建各种合成有用的γ-和δ-内酰胺,且收率范围从大到优,而且底物范围广。
