A safe and practical method for the preparation of 7α-Thioether and thioester derivatives of spironolactone

Spironolactone is a renal competitive aldosterone antagonist. One of its most important metabolite is the 7α-methylthio spironolactone: thus it is very important to have an efficient and safe access to this compound, for pharmacokinetic studies. In this context, we synthesized this metabolite by thioalkylation of 7α-Thio spironolactone using Hu?nig's base with a very good yield. We also used our procedure to prepare, with an easy work-up and high yields, 7α-Thioether and thioester derivatives of spironolactone, that could be useful for further Structure-Activity Relationships studies.
