synthesized by a copper-catalyzed multicomponent domino reaction of oxime esters, terminal ynones, sulfonyl azides, aryl aldehydes and acetic ammonium. Its synthetic pathway involves the formation of a highly reactive N-sulfonyl acetylketenimine, characterized by high selectivity, combinations of potential nucleophiles and electrophiles, mild reaction conditions and a wide substrate scope, and is a rare
通过肟酯、末端炔酮、磺酰叠氮化物、芳基醛和乙酸铵的铜催化多组分多米诺反应合成了药用和合成重要的烟酰胺库。其合成途径涉及形成高反应性的N-磺酰基乙酰酮亚胺,具有选择性高、潜在的亲核试剂和亲电试剂组合、反应条件温和、底物范围广等特点,是少有的CuAAC/环五组分实例。打开反应。
