The 21-thioalkanoic acids of corticosteroids were obtained as a result of nucleophilic substitution in the reaction of the 21-sulfonic esters and 21-halogeno derivatives of corticosteroids with the thiolates of mercaptoalkanoic acids.The thiolates were synthesized by the action of bases on the corresponding mercaptoalkanoic acids.The 21-thioalkanoic acids of the corticosteroids were also obtained by the reaction of the 21-chloro and 21-bromo derivatives of the corticosteroids with mercaptoalkanoic acids in dipolar aprotic solvents.
