The challenging vicinal quaternary and tertiary stereocenters of the 5,10b-ethanophenanthridine skeleton are created in a single step utilizing intramolecular [3 + 2]-cycloaddition of nonstabilized azomethine ylide as the key step. The application of the chemistry is demonstrated by synthesizing (+/-)-maritidine.
5,10b-乙菲啶骨架中具有挑战性的邻位季碳和叔碳立体中心是通过分子内[3+2]环加成非稳定甲亚胺叶立德作为关键步骤一步构建而成的。通过合成(±)-马里替丁证明了该化学方法的应用。
