dc.description.abstract	On exposure to the potential carcinogen 1,3-butadiene, the major urinary metabolite in humans is N-acetyl-S-(3,4-dihydroxybutyl)cysteine. A novel, stereoselective synthesis of this cysteine–butadiene metabolite has been developed that is suitable for the production of either diastereomer for use in occupational exposure analysis. L-Cysteine and 4-bromo-1-butene are coupled via an SN2 reaction to give the core structure. A Sharpless asymmetric dihydroxylation using the dihydroquinidine (DHQD) ligand provided the terminal 1,2-diol with the 3-hydroxyl group in the R configuration.
