The synthesis of [1,2,3,4-13C] cortisol.
The preparation of [1,2,3,4-13C] cortisol 21 acetate by total synthesis is described. The C labels are introduced in a way analogous to the one described by us previously for the synthesis of testosterone and estradiol. The cortisol dihydroxyacetone side chain was elaborated using known methods. The 11 beta-hydroxyl function was introduced by addition of hypobromous acid to a 9-double bond followed by reductive debromination. 13C-labeled cortisol can be used as a tracer for the determination of cortisol production rates.
