Chemical syntheses of 1-(2-deoxy-beta-D-ribofuranosyl)lumazines and isopterins as well as 8-(2-deoxy-beta-D-ribofuranosyl)-4-amino-7(8H)pteridones and -isoxanthopterins have been developed to make the structural analogs of the naturally occurring 2'-deoxyribonucleosides in the pteridine series available. The corresponding phosphoramidites have been used in machine-aided solid-support syntheses leading to new types of fluorescence labeled oligonucleotides. The effects of the various fluorophors on duplex formation and as labels for enzyme reactions is demonstrated.
