synthetic chemist. The topologically interesting isopavine nucleus, with an orthogonal orientation of two aryl groups, can be obtained as two diastereomeric structures, depending on the course of a [1,2]-Stevens rearrangement. When viewed as a constrained piperidine, a close spatial relationship with morphine (1) becomes apparent. Indeed, tetracyclic isopavine 2 exhibits morphine-like activity toward the
