Studies on the syntheses of analgesics. Part XXXVI . Synthesis of 1,2,3,4,5,6‐ilexahydro‐2,6‐methano‐6‐phenyl‐2 henzazocine [studies on the syntheses of heterocyclic compounds. Part D XI ]

An attempt to obtain 2,3,4,5,6,7‐hexahydro‐l H 2,7‐methano‐9‐methoxy‐3‐rnethyl‐7‐phenyl‐2,3‐benzodiazonine (II) by the Pictet‐Spengler reaction of 2,3,4,5,6,7‐hexahydro‐l H ‐4‐(3‐meth‐oxyphenyl)‐l‐methyl‐4‐phenyl‐1,2‐diazepine (XI) prepared through several steps from 1‐(3‐methoxyphenyl)phenylaeetonitrile (IV) resulted instead, in the formation of 1,2,3,4,5,6‐hexa‐hydro‐2,6‐methano‐8‐methoxy‐6‐phenyl‐2‐benzazocine (XIV).
