(2,2-2H2)Sparteine, (6-2H)sparteine, (10,10-2H2)sparteine, (15,15-2H2)sparteine, (17α-2H)sparteine, (17β-2H)sparteine, (17,17-2H2)sparteine, (17α-2H)lupanine, and (17β-2H)lupanine were prepared and employed to assign the 1H nmr spectrum of sparteine.Contrary to a published report, photochemical oxidation of sparteine does not lead to 15-oxosparteine but to 17-oxosparteine.
