occasion of his 60th birthday Abstract The consecutive four-component synthesis of 5-acylpyridin-2(1H)-ones initiated by a copper-free alkynylation in a one-pot fashion has been expanded to include considerably less nucleophilic anilines as the amine component in the Michael addition step by altering the solvent system to 1,4-dioxane; 17 examples for the synthesis of 1-aryl-5-benzoyl-6-phenyl-3,4-dihyd
专用于克劳斯教授特奥多尔·沃纳在他60之际个生日 抽象 通过一锅法由无铜炔基化反应引发的5-酰基吡啶-2-2(1 H)-one的连续四组分合成方法已得到扩展,在迈克尔加成步骤中,胺类组分的亲核苯胺数量大大减少,将溶剂体系改为1,4-二恶烷; 以中等至良好的产率获得了用于合成1-芳基-5-苯甲酰基-6-苯基-3,4-二氢吡啶-2-2 (1 H)-的17个实施例。 通过一锅法由无铜炔基化反应引发的5-酰基吡啶-2-2(1 H)-one的连续四组分合成方法已得到扩展,在迈克尔加成步骤中,胺类组分的亲核苯胺数量大大减少,将溶剂体系改为1,4-二恶烷; 以中等至良好的产率获得了用于合成1-芳基-5-苯甲酰基-6-苯基-3,4-二氢吡啶-2-2 (1 H)-的17个实施例。
