A bismuth(III) triflate catalyzed three-component synthesis of α-substituted amides starting from amides, aldehydes, and (hetero)arenes is reported. The reaction has a broad substrate scope, encompassing formaldehyde as well as aryl and alkyl aldehydes. Low catalyst loadings are required, and water is formed as the only side product. The scope and limitation of this method will be discussed.
报道了三氟甲磺酸铋(III)从酰胺,醛和(杂)芳烃开始催化α-取代酰胺的三组分合成。该反应具有广泛的底物范围,涵盖甲醛以及芳基和烷基醛。需要低的催化剂负载量,并且形成水作为唯一的副产物。将讨论此方法的范围和局限性。
