We report here on the syntheses of three deuterium-labeled tobacco-specific nitrosamines namely [2,4,5,6-d4]nitroso-nornicotine([2,4,5,6-d 4]NNN), 4-(methylnitrosamino)-1-(3-[2,4,5,6-d4]pyridyl)-1- butanone ([2,4,5,6-d4]NNK), and 4-(methyl-nitrosamino)-1-(3-[2,4,5,6- d4]pyridyl)-1-butanol ([2,4,5,6-d4]NNAL). A metabolite of NNK and myosmine, 4-hydroxy-1-(3-[2,4,5,6-d4]pyridyl)-1-butanone, was also synthesized. The synthetic strategy reported here is similar to that reported in the literature for the preparation of corresponding unlabeled compounds. The commercially available [2,4,5,6-d4]ethylnicotinate was used as starting material. During the course of these syntheses [2,4,5,6-d 4]myosmme and [2,4,5,6-d4]nornicotine were obtained as stable intermediates. These isotope-labeled compounds are useful internal standards for quantification of TSNA and their metabolites in smokers in molecular epidemiological studies. Copyright
Synthesis of partially deuterated N-nitrosamines - New standards in tobacco-smoke analysis
Gaertner, Peter,Bica, Katharina,Einzinger, Christian
, p. 549 - 555 (2007/10/03)
N-Nitrosamines of tobacco alkaloids contribute to the cause of tobacco related cancers and, therefore, they are important analytes. Herein the preparation of four partially deuterated N-nitrosamines from simple, commercially available, deuterated educts is described, which can serve as useful standards in tobacco-smoke analysis.
