primary amines with 2-phenyl-4-phenylmethylene-2-oxazolin-5-one using acidic alumina or montmorillonite K 10 clay undermicrowaveirradiation (MWI). The same reaction over basic alumina gave arylamides of α-arylamido-β-arylacrylic acids in good yield. Usage of acidic alumina for cyclization gave better results in comparison with clay. This procedure highlights the versatility of various solid supports
1,2-Diaryl-4-phenylmethylene-2-imidazolin-5-ones 是由伯胺与 2-phenyl-4-phenylmethylene-2-oxazolin-5-one 使用酸性氧化铝或蒙脱石 K 10 粘土在微波辐射(MWI)。在碱性氧化铝上进行相同的反应以良好的收率得到α-芳基氨基-β-芳基丙烯酸的芳基酰胺。与粘土相比,使用酸性氧化铝进行环化产生了更好的结果。该程序突出了各种固体支持物的多功能性。
