Several 2-glycosylaminopyridines 7, were synthesized through a tandem
Diels-Alder/Retro Diels-Alder (DA/RDA) reaction starting from 6-glycos
ylaminopyrimidines, 6, with dimethyl acetylenedicarboxylate (DMAD) as
dienophile. This approach represents a new method for the synthesis of
2-aminopyridine nucleoside analogues. The compounds were tested for t
heir antiviral activity but did not prove active. Copyright (C) 1996 E
