A Practical Synthesis of Regioisomeric 6- and 7-Methoxytetrahydro-3-benzazepines
摘要:
A concise and versatile synthetic route for 6- and 7-methoxy tetrahydro-3-benzazepines is described. The key feature of the synthesis is a one-pot acylatioti/cyclizaition/elimination sequence to construct either of the isomeric dihydrobenzazepine ring systems from the same starting material. The route is high yielding and chromatography-free.
