Abstract Various carbocyclic nucleosides analogs of neplanocin A (such as 5- aminoimidazole-4-carboxamide riboside, uridine, 5-iodouridine, 4-thiouridine, cytidine, thymidine, 2′-deoxyguanosine, ribofuranosylthymine, a 2, 2′-anhydroderivative, 2′- deoxycytidine, 2′-deoxythiouridine, and d-arabinofuranosylcytosine analogs) were synthesized from (1R, 2S, 3R)-2, 3-isopropylidenedioxy-4-methoxymethyloxymethyl-4- ...
