substituted pyrrole derivative. This derivative could be transformed into the pyrrole‐containing secondary metabolite, rhazinilam, which could in turn be transformed through a reductive transannular cascade process into the structurally complex pyrrolidine‐containing alkaloid natural product, aspidospermidine.
