An efficient and general synthesis of substituted 2-amino-7,8-dihydropteridin-6(5H)-ones using a combination of solution-phase and solid-phase chemistry is described. Solution-phase chemistry was used to produce two pyrimidine regioisomers that were

6-Acylmino-1-alkyl/aryl-4-oxo-1,4-dihydrocinnoline-3-carboxamides were synthesized in parallel from 6-nitro-4-oxo-1,4-dihydrocinnoline-3-carboxylic acid. The latter formed amides with amines bound to polystyrene-based resins via acid-labile linkers.

The following paper summarizes our work on compound libraries of 2,6,8-trisubstituted purines. This synthesis route on a polystyrene support begins with 2,6-dichloro purine making extensive use of catalysis. During the synthesis the polymer bound pur
