Abstract
Synthesis of alkaloids, cleistopholine, oxylopine (isoursuline), ursuline, and related compounds by application of a method for constructing cycloalkenopyridines was described and the synthesis revealed that the structure of oxylopine should be revised to 6-hydroxy-5-methoxyonychine from 5-hydroxy-6-methoxyonychine.
