2 H N.m.r.Spectroscopy has been used to establish the labelling patterns in sparteine (3), lupanine (5), and angustifoline (7), derived biosynthetically from (R)-[1-2H]-(8) and (S)[1-2H]-cadaverine (9); the presence of 2H at C-17 in these three alkaloids from the former precursor (8) demonstrates that 17-oxosparteine cannot be an intermediate in quinolizidine alkaloid biosynthesis.
