N-Acylated amines are ubiquitous in nature. Selective N-acylation at neutral conditions remains a key area of interest. Here we are reporting the copper sulfate-mediated highly selective, mild, and rapid N-acylation of various aliphatic and aromatic amines using thioacids in methanol at neutral conditions. All N-acylated products of primary and secondary amines were isolated in good to excellent yields
N-酰化胺在自然界中无处不在。在中性条件下的选择性N-酰化仍然是重要的关注领域。在这里,我们报道了在中性条件下,使用
硫酸在
甲醇中通过
硫酸铜介导的各种脂肪族和芳香族胺的高选择性,温和和快速的N-酰化反应。分离出所有
伯胺和仲胺的N-酰化产物,收率良好至优异。发现该方法对胺具有高度选择性,并且对其他官能团(例如
酚,醇和
硫醇)不敏感。该反应的简单后处理,高收率和高选择性可以替代现有的酰基卤和酸酐介导的N-酰化反应的那些。
