Aldehyde or ketone compounds having more than one carbonyl group are reductively aminated to form a product amine compound having more than one primary amino group. The aldehyde or ketone compound is reacted with the product amine compound in the presence of an alcohol solvent, to form a reaction mixture that contains one or more intermediates. The intermediate is then reductively aminated to form the desired product. This process may produce the desired product in very high yields with low levels of secondary amine impurities.
具有多个羰基基团的醛或酮化合物通过还原胺化反应形成具有多个一级
氨基团的产物胺化合物。在醇溶剂存在下,将醛或酮化合物与产物胺化合物反应,形成含有一个或多个中间体的反应混合物。然后,将中间体还原胺化反应形成所需的产物。该过程可产生高收率且含有低
水平的二级胺杂质的所需产物。
