Various α-acyloxy carboxyamides were easily obtained combining three building blocks in one step: a carboxylic acid, an aldehyde and an isonitrile (Passerini reaction), using microwave irradiation under solvent-free conditions. The products were obtained in good yields (61-90%) and in short reaction times (< 5 min), using two different temperatures (60 and 120 ºC). At 120 ºC, the yields were higher and the reactions faster (< 1 min). Most of the obtained products are multifunctional allowing their application in consecutive Passerini reactions
各种 α-酰氧基羧酰胺可以通过将三种构建块在一步中结合获得:一种
羧酸、一种醛和一种
异氰酸酯(帕塞里尼反应),使用微波辐射在无溶剂条件下进行。产物的收率良好(61-90%),反应时间短(< 5 分钟),使用两种不同的温度(60 和 120 ºC)。在 120 ºC 时,收率更高,反应更快(< 1 分钟)。大多数获得的产物是多功能的,允许在连续的帕塞里尼反应中应用。
