This work describes acylation reactions facilitated by a type of heterocycle‐based acyl transfer agent, 2‐acyloxypyridazinone. Reactions of 2‐acyloxypyridazinone with carboxylic acids yield mixed carbonic anhydride intermediates, which are reactive and could be coupled with a wide range of substrates including acids, amines, alcohols, and thiols. The wide substrate scope, ease of operation (no additive
这项工作描述了一种基于杂环的酰基转移剂2-酰氧基吡啶并嗪酮促进的酰化反应。2-酰氧基哒嗪酮与羧酸的反应产生混合的碳酸酐中间体,该中间体具有反应性,并且可以与多种底物偶联,包括酸,胺,醇和硫醇。广泛的底物范围,易操作性(无添加剂或催化剂),储存和处理稳定性以及回收杂环载体带来的原子效率使所报道的酰化剂对基于酰化的偶联反应具有吸引力。
