synthesized by an oxidative amidation in the presence of dibromoisocyanuric acid (DBI). Treatment of aromatic and aliphatic aldehydes with dibromoisocyanuric acid generated acyl bromide intermediates, which were employed to react with a variety of secondary and primary amines to give amides. Through this reaction method, various amides were synthesized directly from aldehydes under mild conditions in high yields
描述了一种从醛直接合成酰胺的简便方法。在二溴异氰尿酸(DBI)存在下,通过氧化酰胺化合成酰胺键。用二溴异氰尿酸处理芳族和脂族醛可生成酰基溴中间体,该中间体可与多种仲胺和伯胺反应生成酰胺。通过这种反应方法,可以在温和的条件下以高收率和短时间直接从醛中合成出各种酰胺。这种简便有效的方法为从醛直接合成酰胺提供了潜在的策略。
