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

The Hinsberg thiophene synthesis was expanded to support bound thioglycolic acid derived synthons, which reacted with arils to give thiophenes in high purity.

Oxadiazoles were generated upon a dehydrative cyclization reaction with 2-acyl hydrazides bound to the polymeric support via one of their N atoms using TFAA as a dehydration agent.

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

2,6,8-Trisubstituted purines were synthesized from 2,6-dichloropurine bound to polystyrene-based Rink resin at the N(9) position. Selective successive displacements of the chlorine atoms in the 2- and 6-positions followed. Bromination of C(8) and Sti

Diaminopurines, immobilized on a polymeric support are treated with a charge transfer complex of bromine and lutidine to afford 8-brominated derivatives. An ionic complex of bromine and lutidine did not oxidize the purines. 2,6-Dialkylaminopurines co
