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 cyclization, an intramolecular reductive cyclization, and an oxidation.
我们提出了一种从四组分 Ugi-Smiles 反应和随后的三步级联反应(包括酸催化环化、分子内还原环化和氧化)起始,高效合成融合苯并咪唑哌嗪的新方法。
