The possibility of deriving a potent, cell-penetrating inhibitor of humanerythrocyte PI 4-kinase, competitive with respect to ATP, has been investigated in a series of purine derivatives and analogues. The purine nucleus is not essential for binding to the ATP site but offers the advantage of synthetic accessibility to its derivatives. The optimum substitution pattern in purine was found to be an

A series of N3 and N9 aryladenines was prepared by arylation of 8-bromoadenine under modified Chan-Lam-Evans coupling conditions followed by reductive debromination with hydrogen on palladium. Conditions of arylation were optimised to maximise the yield of N3-arylated products. The selectivity of the reaction varied with temperature the ligand used. The best results were obtained in DMF with phenanthroline as a ligand at 60 degrees C.

A Mild and Efficient Method for<i>N</i>‐Arylnucleobase Synthesis<i>via</i>the Cross‐Coupling Reactions of Nucleobases with Arylboronic Acids Catalyzed by Simple Copper Salts
A simple and efficient copper-salt catalyzed N-arylation of nucleobases is reported. In a mixed solvent of MeOH and H2O, the coupling products were obtained in moderate to excellent yields at room temperature within a short time. A variety of substituted N-aryl nucleobases can be prepared through this procedure.
