straightforward methodology to regioselectively phosphorylate the 5′-OH group of unprotected nucleosides. We employ cyclosaligenyl phosphoramiditereagents together with pyridinium trifluoroacetate as activator, followed by in situ oxidation to prepare a panel of novel nucleoside-based chemical probes, ProLabel compounds 4–15. Alternative procedures for this transformation are available, but are limited

The synthesis of cycloSal-FdUMP 3a-d as a new prodrug approach for FdU 1 is described. Phosphotriesters 3 release the FdUMP 2 selectively by a controlled, chemically induced tandem reaction in hydrolysis studies. The biological activity (IC50) of cycloSal-phosphotriesters 3 was evaluated in FM3A/O cells and FM3A/TK- cells.

The synthesis of cycloSal-d4TMP 3a-g as new pro-nucleotide approach for d4TMP 2 is described. Phosphotriesters 3 release the d4TMP 2 selectively by a controlled, chemically induced tandem reaction. CycloSal-phosphotriesters 3 exhibited high biological activity against HIV-1/HIV-2 in CEM cells which was completely retained in CEM TK- cells.
