Synthesis of ethyl (9-hypoxanthinyl)- and (9-adeninyl)acetates, ethyl 3-(9-hypoxanthinyl)- and 3-(9-adeninyl)propanoates, and ethyl 2-(9-hypoxanthinyl)- and 2-(9-adeninyl)propanoates from appropriately substituted 5-aminoimidazole precursors is described. Cyclisation of the imidazoles also resulted in formation of an imidazopyrimidine and novel imidazoimidazoles.
