difunctionalization through direct and selective activation of aliphatic C−H bonds. Compared with previous studies, the significant advantages of this strategy are that the most abundant hydrocarbons are used as feedstocks, and various highly functionalized tertiary, secondary, and primary C(sp3)‐hybrid centers can be easily installed. The practicability of this strategy is demonstrated in the selective late‐stage
催化烯烃双官能化是快速组装复杂分子的强大策略,在合成化学中具有广泛的应用。尽管取得了重大进展,但仍需要解决的一个迫切挑战是安装高度功能化的C(sp 3)杂交中心,无需预先活化的底物。我们在此报告,廉价且易于合成的十分解钨酸光HAT与镍催化相结合,通过直接和选择性活化脂肪族CH键为三组分烯烃双官能化提供了一个多功能平台。与以前的研究相比,此策略的显着优势在于,可以使用最丰富的碳氢化合物作为原料,并且可以轻松地安装各种高度官能化的叔,仲和伯C(sp 3)杂交中心。天然产物的选择性后期功能化和包括吡拉列汀在内的药物相关分子的简明合成证明了该策略的实用性。
