Process for the preparation of C-nucleosides and C-nucleoside analogues, new C-nucleosides and C-nucleoside analogues and their use

摘要

New nucleosides having general formula (I), their preparation and their use are disclosed. These nucleosides show a therapeutic, in particular virostatic and cancerostatic action, and are very stable in comparison with analogous compounds. In addition, these compounds may be used as building blocks of synthetic oligonucleotides (ribo or 2'-desoxyribo forms).
