been developed as chemoselective N-acylation reagents. Selective protection of primary amines in the presence of secondary amines, acylation of aliphatic amines in the presence of aryl amines, and monofunctionalization of primary-secondary diamines as well as selective N-acylation of amino alcohols using these reagents are described. All of the acylation reactions were carried out in water as a green
摘要 多种 N-酰基-N-(4-氯苯基)-4-硝基苯磺酰胺 (1a-e) 在无溶剂条件下由 4-氯苯胺在一锅中合成,并已被开发为化学选择性 N-酰化试剂。描述了在仲胺存在下伯胺的选择性保护、芳胺存在下脂肪胺的酰化、伯仲二胺的单官能化以及使用这些试剂的氨基醇的选择性 N-酰化。所有酰化反应均在作为绿色溶剂的水中进行。这些酰化试剂的高稳定性和易于制备是该方法的其他优点。
