Although photoredox catalysis is already known for synthesizing amines, the synthesis of linear aliphatic amines is mostly limited to hydroaminomethylation (HAM) reactions and has never been applied to the synthesis of longer-chain linear aliphatic primary amines. Considering this, the synthesis of functionalized linear aliphatic primary amines is demonstrated by using the decarboxylative radical-polar
脂肪族伯胺至关重要,每年至少需要数百万吨。因此,人们对寻找新的合成化学路线产生了浓厚的兴趣。此外,为了符合可持续性要求,高度优先考虑使用廉价原料的合成路线。在这方面,由于烯烃的广泛可用性和较低的价格,加氢氨基烷基化(HAA)反应是非常理想的。尽管光氧化还原催化已知用于合成胺,但直链脂肪胺的合成主要限于加氢氨甲基化(HAM)反应,并且从未应用于长链直链脂肪伯胺的合成。考虑到这一点,通过使用脱羧自由基-极性交叉工艺证明了官能化直链脂肪伯胺的合成,该方法以优异的收率产生了多种官能化直链脂肪胺。该方法的优势通过现有药物的合成和复杂药物的后期转化得到证明,并通过详细的机理研究进行了阐述。
