We had found the novel N-alkylation method, which utilizes carboxylic acids as alkyl sources with sodium triacetoxyborohydride [NaBH(OAc)3]. Our methodology had been revealed to have some advantages over the reported similar procedures. Through the further investigation about our method, it was disclosed that acetonitrile was the suitable solvent and N-alkylation for aliphatic amines were also smoothly
我们发现了新颖的N-烷基化方法,该方法利用羧酸作为烷基源与三乙酰氧基硼氢化钠[NaBH(OAc)3 ]。我们的方法已被证明比报道的类似程序有一些优势。通过对我们方法的进一步研究,公开了乙腈是合适的溶剂,并且脂肪族胺的N-烷基化也顺利进行。在研究的过程中,我们发现通过使用旧的含THF的过氧化物材料将4-羟丁基部分诱导为苯胺。
