1-(2-Pyridyl)-2-propen-1-ol showed an unprecedented reactivity behaving as Hantzsch ester 1,4-dihydropyridine mimic for the metal-free reduction of the nitro group of electron-deficient aromatic and heteroaromatic nitro compounds to the corresponding amino function. The redox mechanism is part of a domino process involving a direct trapping of the amino derivatives through aza-Michael addition to the
1-(2-吡啶基)-2-丙烯-1-醇表现出空前的反应活性,因为Hantzsch酯1,4-二氢吡啶模拟物可将电子不足的芳族和杂芳族硝基化合物的硝基无金属还原为氨基。相应的氨基功能。氧化还原机制是多米诺骨牌过程的一部分,该过程涉及通过将氮杂-迈克尔加成到乙烯基酮中间体中而直接捕获氨基衍生物,从而导致一锅形成新的官能化氨基酰基吡啶。
