Synthesis and analytics of 2,2,3,4,4-d5-19-nor-5α-androsterone—An internal standard in doping analysis
摘要:
A short and efficient synthesis of pentadeuterated 2,2,3,4,4-d(5)-19-nor-5 alpha-androsterone 7 starting from 19-noralidrost-4-ene-3,17-dione 1 by a d(1)-L-Selectride mediated stereo- and regioselective reduction of the 3-keto group is presented. The use of compound 7 as internal standard for the detection of anabolic steroids via mass spectrometric techniques such as gas chromatography-mass spectrometry (GC-MS) is discussed.
