Mechanosynthesis of pharmaceutically relevant sulfonyl-(thio)ureas

Tan, Davin,?trukil, Vjekoslav,Mottillo, Cristina,Fri??i?, Tomislav

, p. 5248 - 5250 (2014)

We demonstrate the first application of mechanochemistry to conduct the synthesis of sulfonyl-(thio)ureas, including known anti-diabetic drugs tolbutamide, chlorpropamide and glibenclamide, in good to excellent isolated yields by either stoichiometric base-assisted or copper-catalysed coupling of sulfonamides and iso(thio)cyanates. the Partner Organisations 2014.
