AB Reaction of 6-chloro,9-(2-acetoxyethoxymethyl)purine 1 with ethyl
cynoacetat, malononitrile and diethyl malonate in presence of NaH and
DMF yielded the corresponding 6-methylidene derivatives 2a-c, which were
deprotected by treatment with methanolic Ammonia to yield 3a-c. During
the reaction of 1 with cyanoacetamide deacetylation took place
spontaneously resulting in the deprotected acyclic nucleoside 4.
Treatment of 2a with methyliodide in presence of NaH and DMF yielded the
N-methyl derivative 5. NMR and mass spectra of the synthesized compounds
are discussed.
