This invention relates to novel unsaturated acyclic phosphonate derivatives of certain purine or pyrimidines useful as anti-viral agents and as purine nucleoside phosphorylase inhibitors, to methods and intermediates useful for their preparation and to their end-use application as immunosuppressants, anti-lymphoma, anti-leukemic, anti-viral and antiprotozoal agents and also as agents used in conjunctive therapy to potentiate the efficacy of anti-viral nucleoside analogs which would otherwise become subject to the enzymative action of purine nucleoside phosphorylase.

Alkylation of adenine (5a) or 2-amino-6-chloropurine (5b) with excess trans-1,4-dichloro-2-butene (4), effected by K2CO3 in dimethyl sulfoxide or tetra-n-butylammonium fluoride in tetrahydrofuran, led in 90-95% regioselectivity to 9-alkylpurines 6a and 6b. The title compounds 2a and 2b were obtained by refluxing intermediates 6a and 6b in 0.1 M NaOH or HCl. Adenine derivative 2a is a substrate for
