achieved starting from the corresponding aldehydes and amines. The synthesis features three oxidative reactions as key steps in a biomimetic manner, involving an AgOAc-mediated oxidative coupling reaction to construct the pyrrole core, a Pb(OAc)4-induced oxidative cyclization to form the lactone, and Kita’s oxidation reaction to form the pyrrole−arene C−C bond.
