A metal-free system has been discovered for the efficient α-oxygenation of tertiary amines to the corresponding amides using oxygen as an oxidant. This visible-light-mediated oxygenation reaction exhibited excellent substrates scope under mild reaction conditions and generated water as the only byproduct. The synthetic utility of this approach has been demonstrated by applying onto drug molecules. At the end, detailed mechanistic reactions clearly showed the role of oxygen and the photocatalyst.

(+)-17-Thionosparteine and its perchlorate have been obtained and characterized by IR and NMR-spectroscopy as well as by X-ray diffraction analysis. Introduction of the thiolactam group into the cis-quinolizidine system causes conformational rigidity of t

(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.
