A search of the literature revealed that ribosylnucleosides of% substituted purines had not yet been prepared. Because of the potential usefulness that some 2-substituted purine ribonucleosides would have as anticancer agents, we extended our studies to include this important area. Since the value of G-chloro-9-PD-ribofuranosylpurine as an intermediate for the preparation of some G-substi-stuted-9-/?-D-ribofuranosylpurines has been ...
