摘要

3 forward synthesis of 4 could be envisioned as a one-step Gomberg-Bachmann-Hey aryl coupling reaction3 between readily available 4-aminopyrazolo [3, 4-d] pyrimidines (5) 4 and a variety of aromatic solvents. This method would allow for specific control of the site for arylation as well as for the preparation of numerous analogues from only a few common radical intermediates. A similar approach to the preparation of 6, the purine analogue of 4, ...
