acids with primary and secondary amines under a variety of conditions (reflux, sealed tube, microwave) has been compared for a significant range of coupling partners of relevance to the preparation of amides of interest in pharmaceutical chemistry. Commercial microwave reactors promote the fastest couplings and allow the use of significantly sterically hindered amines (primary and secondary) and carboxylic
的范围和DABAL-ME的效用3个甲基酯和游离羧酸与在各种条件下伯和仲胺(回流,密封管,微波)的联接器相比已经用于显著范围耦合相关的伙伴制备的医药化学中感兴趣的酰胺类化合物。商业微波反应器促进最快的偶联,并允许使用空间位阻显着的胺(伯胺和仲胺)和羧酸衍生物。已显示微波能量对反应系统的影响通常与热效应(过压和过热)有关。
