A convenient synthesis of bisamide from aldehyde and amide with BF3 etherate as catalyst was reported. Both aryl and aliphatic bisamides could be prepared with this procedure in high yield at room temperature and the catalyst loading as low as 0.5 mol % was achieved. Fine-tuned solvent was utilized for both rapid conversion and simple isolation. Two CB2 receptor inverse agonists were synthesized with
从醛和酰胺与BF双酰胺的一种方便的合成3作为报道醚合物催化剂。可以通过该方法在室温下以高收率制备芳基和脂族双酰胺,并且催化剂的负载量低至0.5 mol%。微调的溶剂可用于快速转化和简单分离。两个CB 2受体反向激动剂,用该协议以高收率合成。
