—— | 3-{2-[(diisopropoxyphosphoryl)methoxy]ethyl}-6-propylfuro[2,3-d]pyrimidin-2(3H)-one | 1238368-13-2 | C18H29N2O6P | 400.412 |
As a part of a broader structure–activity relationship (SAR) study of bicyclic nucleoside analogues (BCNAs) [anti-varicella-zoster virus (anti-VZV) and anti-human cytomegalovirus (anti-HCMV) agents], a novel series of 2-(phosphonomethoxy)ethyl (PME) substituted furo[2,3-d]pyrimidin-2(3H)-ones was synthesized. The target acyclic nucleotide analogues were prepared by Sonogashira coupling of protected 5-iodo-1-[2-(phosphonomethoxy)ethyl]uracil with various 1-alkynes, followed by in situ Cu(I)-promoted intramolecular cyclization and standard removal of the isopropyl ester groups. None of the prepared PME analogues were active at subtoxic concentrations against VZV thymidine kinase competent (TK+), VZV thymidine kinase deficient (TK–), HCMV, or any other viruses tested.
