catalytic synthesis of N-arylimidazoles starting from the corresponding N-arylformamides and N-formylglycine esters is described. Application to different aryl substituted electron-withdrawing and -donating groups provided the analogous heterocyclic compounds in very high yields. The use of copper(I) oxide/proline catalysts allowed the reactions to proceed at room temperature. The first synthesis of N-arylimidazole
的直接催化合成Ñ -arylimidazoles从相应的起始Ñ -arylformamides和Ñ甲酰甘氨酸酯进行说明。应用于不同的芳基取代的吸电子和供电子基团以非常高的产率提供了类似的杂环化合物。使用氧化铜(I)/脯氨酸催化剂可使反应在室温下进行。还描述了带有N-芳基咪唑的碳水化合物部分的第一合成。
