catalysed efficient, mild and metal-free method has been developed for direct amide bond synthesis from simple thioacids and amines as starting materials. This methodology is useful for aromatic, aliphatic, and heteroaromatic thioacids as well as primary, secondary, heterocyclic, and even functionalized amines. A wide substrates scope, operationally mild conditions, and acylation of amines without affecting
已开发出一种3,6-二(吡啶-2-基)-1,2,4,5-四嗪(pytz)催化的高效,温和且不含金属的方法,用于从简单的硫代酸和胺类化合物直接合成酰胺键材料。该方法学可用于芳族,脂族和杂芳族硫代酸以及伯,仲,杂环,甚至官能化胺。广泛的底物范围,操作温和的条件以及胺的酰化而不影响其他官能团(例如醇,酯,碳二硫代盐)等,使该策略非常具有吸引力和实用性。
