title: [The synthesis of N2,N6-substituted diaminopurine ribosides].
abstract: A series of new 2,6-substituted diaminopurine riboside derivatives were synthesized by activation of protected xantosine with sulfonyl chlorides followed by treatment with various amines. The relationship between the reactivity of intermediates and the nature of the activating agents was studied.
