The nucleophilic addition reaction between 8 - vinylpurine and mathanol, benzenethiol or diethylmalonate and the cycloaddition between 8 - vinylpurine and cyclopentadiene has been investigated. A series of 8 - substituted purines which and not been reported before were prepared and characterized by elemental analysis, ^1H NMR, ^13^C NMR, ^1H - ^1H NOESY and MS.
