Abstract
An efficient synthesis of 2-halo-O6-(benzotriazol-1-yl)-substituted purine nucleosides has been accomplished via (benzotriazol-1-yloxy)tris(dimethylamino)phosphonium hexafluorophosphate (BOP)-mediated coupling and subsequent halogenation via diazotization of the 2-amino group of various protected guanosines and directly from guanosine itself. These products are amenable to substitution and coupling reactions in the 2- and 6-positions and, accordingly, provide efficient access to highly functionalized purine nucleosides.
