Synthesis and Conformation of Hexahydro‐isoquino[3,2‐a][2]benzazepines of the B‐Homoberbine Type
The two‐step synthesis of the hexahydro‐isoquino[3,2‐a][2]‐benzazepines („B‐homoberbines”︁) 4b‐e is described. The main and some further products of the Bischler‐Napieralski reaction of hydroxyamide 3c were isolated and identified. The conformation of the B‐homoberbines was investigated by X‐ray analysis, spectroscopic methods and dehydrogenation with mercury(II) acetate.
