amide ring-opening reaction to generate sp3-enriched scaffolds has been developed and reported. This methodology enables rapid access to substructures with higher fsp3 values, attracting greater attention within the past few decades. The reaction exhibits a wide reaction scope, featuring a highly sterically hindered phenolic ether, thiophenolic ethers, protected aniline formations, and aliphatic/heteroaromatic
富含 Sp 3的小分子在开发候选药物中发挥着关键作用。在设计具有更大 sp 3特征的类似物时,已经开发并报道了一种利用较少探索的环氮丙啶酰胺开环反应来生成富含 sp 3的支架的方法。这种方法能够快速获取具有更高 fsp 3值的子结构,在过去几十年中引起了更多关注。该反应表现出广泛的反应范围,以高位阻酚醚、苯硫酚醚、受保护的苯胺形成物和含脂肪族/杂芳环的氮丙啶酰胺为底物。此外,该反应通过区域选择性转化提供了形成拥挤叔醚的途径,适用于广泛的药物发现目标、复杂小分子的构建和天然产物合成。开发的支架显示出改善的物理化学性质。
