Multicomponent Synthesis of Fused Benzimidazolopiperazines
摘要:
We present a novel protocol for the efficient synthesis of fused benzimidazolo piperazines starting from a four-component Ugi-Smiles reaction and a subsequent three-step cascade involving an acid-catalyzed cydization, an intramolecular reductive cyclization, and an oxidation.
