- Solvent-free synthesis of thio-alkylxanthines from alkylxanthines using microwave irradiation
-
An expeditious, solvent-free procedure for the conversion of the xanthine bases theophylline, 8-methyltheophylline, caffeine, and theobromine to the corresponding 6-thio and 2,6-dithio derivatives using Lawesson's reagent under microwave irradiation is proposed.
