Synthesis of deuterium-labelled meloxicam and piroxicam
Four step syntheses of deuterium-labelled meloxicam and piroxicam from saccharin via selective CD3I alkylation are described. Labelled oxicams are of great interest for qualitative and/or quantitative isotope dilution-mass spectrometry, coupled with liquid chromatography, currently performed in anti-doping and forensic laboratories.
