Prodrugs are increasingly used as delivery vehicles for pharmaceutical agents that present solubility and/or pharmacokinetic/metabolic issues. In the course of the development of prodrugs for the antitumoral agent thiocoraline, standard coupling reagents and procedures failed to provide the desired target
