摘要

The synthesis and conformational studies of two isomeric 5: 7-fused nucleosides, 4, 5, 7, 8- tetrahydro-6H-3-(@~-ribofuranosyl) imidazo [4, 5-e][1, 4] diazepine-5, &dione (1) and its 1- glycosyl analogue (2), their respective 5'-monoand-diphosphate derivatives (13 and 14), and the corresponding homopolymers (15 and 16) are presented. While 1 is devoid of activity against murine leukemia virus (MuLV) in tissue culture systems, 2 is as active as ...
