We explored the bioinspired o-quinone cofactor catalyzed aerobic primary amine dehydrogenation for a cascade olefination reaction with nine different methyl N-heteroarenes, including pyrimidines, pyrazines, pyridines, quinolines, quinoxolines, benzimidazoles, benzoxazoles, benzthiazoles, and triazines. An o-quinone catalyst phd (1,10-phenanthroline-5,6-dione) combined with a Brønsted acid catalyzed
我们探索了仿生邻醌辅因子催化的有氧伯胺脱氢与九种不同的甲基N-杂芳烃的级联烯化反应,包括嘧啶、吡嗪、吡啶、喹啉、喹啉、苯并咪唑、苯并恶唑、苯并噻唑。一个ø与布朗斯台德酸组合的-quinone催化剂博士(1,10-菲咯啉-5,6-二酮)催化的反应。N-杂芳基芪类化合物在温和条件下以高产率和 ( E )-选择性合成,使用氧气 (1 atm) 作为唯一氧化剂,无需过渡金属盐、配体、化学计量碱或氧化剂。

strategy is operationally simple and scalable and tolerates various functional groups undermild reaction conditions. Notably, an aldehyde and aryl-2-quinoline-2-yl-ethanol intermediate are involved in the catalytic reaction mechanism. The utility of the present procedure is demonstrated through a facilesynthesis of the antifungal drug (E)-2-(2-(pyridin-4-yl)vinyl)quinoline.
