Alkylation of adenine (5a) or 2-amino-6-chloropurine (5b) with excess trans-1, 4-dichloro-2-butene (4), effected by K2C03 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 HC1. Adenine derivative 2a is a substrate for adenosine deaminase whereas both 2a and 2b exhibit 50% inhibition of the growth of murine leukemia L 1210 cell culture at 1 mM concentration.Open-chain nucleoside analogues lacking the 2'-or both 2'-and 3'-carbon fragments of ribofuranose moiety are the subject of considerable current interest. Thus, antiviral agent1 acyclovir (la) is derived from guanosine by re-moving the 2', 3'-carbon fragment. The corresponding adenine analogue lb has a much lower antiviral activity, 1 but it is a substrate for adenosine deaminase. 2 Biologically active open-chain analogues can also be derived from other
