1,5‐di‐O‐acetyl‐2,3‐dideoxy‐3‐phthalimido‐β‐D‐erythro‐pentofuranose (1) with silylated pyrimidinediones 2a–c using the Lewis acid trimethylsilyl triflate as catalyst afforded nucleosides 3a–c and 4a,c which were deprotected with 33% methylamine/ethanol to give the corresponding 3‐aminonucleosides 5a–c and 6. These were reacted with 1,4‐dinitroimidazoles 7a,b to give the 3‐imidazolyldideoxynucleosides
