Synthesis of 2′-Methyl-6-methoxyguanosine from the Parent Ribonucleoside Guanosine
Yuan, Changxia,Chen, Ke,Eastgate, Martin
, p. 4646 - 4652 (2019)
A short and efficient synthesis of the nucleoside fragment contained in the NS5B nucleoside inhibitor BMS-986094 was achieved in 23% overall yield on a gram scale. The synthesis uses the widely available starting material guanosine via a short sequence ending in a Mukaiyama hydration reaction to establish the key tertiary alcohol moiety and set the C-2′ methyl stereogenic center. This work resulted in a robust and scalable approach to this complex nucleoside.

We have previously reported the power of combining a 5′- phosphoramidate ProTide, phosphate pro-drug, motif with a 6-methoxy purine pro-drug entity to generate highly potent anti-HCV agents, leading to agents in clinical trial. We herein extend this work with the disclosure that a variety of alternative 6-substituents are tolerated. Several compounds exceed the potency of the prior 6-methoxy leads, and in almost every case the ProTide is several orders of magnitude more potent than the parent nucleoside. We also demonstrate that these agents act as pro-drugs of 2′-C-methyl guanosine monophosphate. We have also reported the novel use of hepatocyte cell lysate as an ex vivo model for ProTide metabolism.
