We herein developed a reductive transamidation reaction between N-acyl benzotriazoles (AcBt) and organic nitro compounds or NaNO2 under mild conditions. This protocol employed the stable and readily available B2(OH)4 as the reducing agent and H2O as the ideal solvent. N-Deuterated amides can be synthesized when conducting the reaction in D2O. A reasonable reactionmechanism involving bond metathesis
我们在此开发了N -酰基苯并三唑 (AcBt) 与有机硝基化合物或 NaNO 2在温和条件下的还原转酰胺基反应。该方案使用稳定且易于获得的 B 2 (OH) 4作为还原剂,使用 H 2 O 作为理想溶剂。当在 D 2 O中进行反应时,可以合成N-氘代酰胺。提出了一个合理的反应机制,包括 AcBt 酰胺和氨基硼酸中间体之间的键复分解,以解释 AcBt 的独特性质。
