Research output: Contribution to journalArticlepeer-review


Synthesis of novel pyridine-stretched nucleoside (PSN) analogues of adenine (strA) (1), 2,6-diaminopurine (strD) (15) and hypoxanthine (strH) (17) from 4(5)-nitroimidazole has been achieved. Glycosylation of 4(5)-nitroimidazole was optimized to give consistently good yields (>70%) of the desired analytically pure 5-nitro-1′-β isomer 8 which on hydrogenation, C-addition of ethoxymethylene malononitrile (EMMN) and cyclisation provides the key intermediate 14 for PSN synthesis.
