Some Aspects of Stereoselectivity in the Introduction of Tritium into Steroids
The continuous increase in the use of radioisotopes as tracers for biological reactions and pathways renders imperative the exact determination of label position and label stability. The following examples represent typical cases involving isotopic substitution outside as well as within† the reaction center.
