A series of di-(adenosin-N6-yl) alkanes (1b)-(1l) has been prepared by reaction of the appropriate diaminoalkanes with 6-chloro-9-β-D-(2, 3, 5-tri-O-acetyl)-ribofuranosyl-purine (2) followed by ammonolysis. Alternatively, an analogous reaction with 6-chloro-9-β-D-(2, 3- O-isopropylidene)-ribofuranosylpurine (3) produced an intermediate which could be phosphorylated at the 5'-position prior to hydrolytic removal of the isopropylidene group. 4 ...
