urinary long-term metabolite “M3” (4-chloro-17β-hydroxymethyl-17α-methyl-18-norandrost-13-en-3-ol) of the common doping agent DHCMT has thus far been detected via GC/MS-MS, creating ambiguities concerning its absolute configuration. Its structure was elucidated via the synthesis of all eight possible stereoisomers with 17β-hydroxymethyl configuration. The highlights of the synthesis consist of a novel
metabolites of oralturinabol (anabolic androgenic steroid restricted in sport). The synthesis of 4-chloro-17β-(hydroxymethyl)-17α-methyl-18-norandrosta-4,13-diene-3α-ol was achieved. Isomerisation of configuration of 13-carbon was used for construction of 17β-(hydroxymethyl)-17α-methyl fragment. The proposed route of synthesis allows to obtain 3β-hydroxy isomer as well .
