Microwave-assisted solvent-free parallel synthesis of thioamides
Rapid parallel synthesis of thioamides is described. A library of amides, synthesised by mixing acyl chlorides and diamines, was transformed into the corresponding thioamides utilising Lawesson's reagent as the oxygen/sulphur exchange reagent. Purification by solid-phase extraction afforded the library members in adequate purities and yields. (C) 2000 Elsevier Science Ltd.
