5-b]indole and 7,12-dihydro-6H-benzo[2,3]oxepino[4,5-b]indole derivatives under mild conditions. This annulation process involves the intramolecular cyclization of the in situ generated ketimine moiety via the formation of dihydrospiroindolequinoline, which serves as a key intermediate in the reaction pathway. Several control experiments and spectroscopic studies were performed to elucidate the underlying
我们开发了一种简单有效的合成方案来生产 5,6,7,12-四氢苯并[2,3]氮杂[4,5- b ]吲哚和 7,12-二氢-6 H-苯并[2,3] oxepino[4,5- b ]吲哚衍生物在温和条件下。该成环过程涉及通过形成二氢螺吲哚喹啉(作为反应途径中的关键中间体)原位生成的酮亚胺部分的分子内环化。进行了一些对照实验和光谱研究以阐明潜在的反应机制。
