catalyzed Sonogashira cross-coupling reaction of aroyl chlorides with aryl acetylenes, and 1,3-dipolar cycloaddition of the 1,3-diarylprop-2-yn-1-ones with sodium azide under catalyst free conditions achieved the synthesis of aryl(4-aryl-1H-1,2,3-triazol-5-yl)methanones in moderate-to-good chemical yields (30–90%). The procedures allowed the synthesis of 4,5-disubstituted-1H-1,2,3-triazol scaffolds containing
摘要分两步进行,在无催化剂的条件下,钯催化了芳酰氯与芳基乙炔的Sonogashira交叉偶联反应,以及1,3,2-二芳基丙-2-yn-1-one与叠氮化钠的1,3-偶极环加成反应合成芳基(4-芳基-1 H -1,2,3-三唑-5-基)甲烷酮,化学收率中等至良好(30-90%)。该程序允许合成含有电子中性,吸电子基团或供体基团的4,5-二取代的-1 H -1,2,3-三唑支架。 图形摘要
