An unprecedented electrochemical cross-dehydrogenative coupling reaction between isochroman and unactivated ketones to directly synthesize α-substituted isochromans has been developed. This strategy provides a facile and efficient procedure to the direct activation of C(sp3)–H bond adjacent to the O atom of isochroman. The method features high atom economy, chemical oxidant-free, and mild conditions
开发了
异色满和未活化酮之间前所未有的电
化学交叉脱氢偶联反应,可直接合成 α-取代的
异色满。该策略为直接激活与
异色满的 O 原子相邻的C(sp 3 )-H 键提供了一种简便有效的方法。该方法具有原子经济性高、无
化学氧化剂、条件温和等特点,其中
甲磺酸(MsOH)既作为电解质又作为催化剂,使该过程更加便捷和环保。抗肿瘤活性化合物的克级实验和合成证明了该协议在实际应用中的巨大潜力。
