Suitable protected 4,4a-anhydro-cyclopentane derivatives have been used for the straightforward of cyclopentanoid nucleoside precursors. Thus, by simple transformations nucleoside precursors modified at the positions C(4), C(4a) and C(4,4a) as well as side-chain modified derivatives were accessible. The structures of the key intermediates were determined by xray analyses.
