‘Rhaz'zmatazz: A total synthesis of (−)‐rhazinilam and the first asymmetric total synthesis of (−)‐rhazinicine were accomplished by using constructing the indolizinone core through the gold‐catalyzed cyclization of a fully elaborated linear ynamide. The scope and generality of this cascade reaction for the construction of highly substituted indolizinones were also investigated.
'Rhaz'zmatazz:(-)-rhazinilam的全合成和(-)-rhazinicine的第一个不对称全合成是通过使用金精催化的完全精制的线性乙酰胺环化吲哚嗪酮核心完成的。还研究了该级联反应用于构建高度取代的吲哚嗪酮的范围和一般性。
