摘要: Novel bicyclonucleoside analogues having an anti-AIDS activity; and intermediates for the preparation of oligonucleotide excellent antisense or antigene activity being stable in vivo . Specifically, compounds represented by structural formula (I) pharmacologically acceptable salts thereof, wherein R is hydrogen a hydroxyl-protecting group; azido, optionally protected amino, like; B purin-9-yl 2-oxo-1,2-dihydropyrimidin-1-yl group which substituted with member selected from consisting halogeno, C1-C6 alkyl, hydroxyl, mercapto, so on.
