title: Biogenetic studies in Mentha x piperita. 1. deuterium-labeled monoterpene ketones: synthesis and stereoselective analysis.
abstract: Pulegone, menthone, and isomenthone isotopomers are synthesized as regioselectively deuterated d(5)- and d(8)-stereoisomers. Deuterium-labeled menthone and isomenthone enantiomers are analyzed using enantioselective multidimensional gas chromatography/mass spectrometry. The deuterated stereoisomers of menthone and isomenthone are separated from the unlabeled menthone and isomenthone on a glass capillary column, coated with 50% octakis(2, 3-di-O-butyryl-6-O-tert- butyldimethylsilyl)-gamma-cyclodextrin in OV 1701vi as the chiral stationary phase. These deuterium-labeled monoterpene ketones are proved to be highly valuable substrates in biosynthetic studies of terpenoid compounds.
