A new synthesis protocol for the preparation of hitherto unknown 1′,5′-anhydro-4′-amino-trityl/MMTr hexitol nucleosides has been developed. Key steps in the synthesis of the pyrimidine analogues (U and C) include the regioselective d-allo-hexitol oxirane and 2′,4′-anhydronucleoside ring opening by uracil and azide, respectively. A different strategy using a regioselective epoxide ring opening of d-gulo-oxirane, followed by a SN2 type of azidation reaction, has been adopted for the purine analogues (A and G). These compounds can be easily converted to 6′-phosphoramidites for the solid-phase synthesis of N4′ → P6′ phosphoramidates of amino hexitol nucleic acids (AHNA).

Four D-altritol nucleosides with a 3′-O-tert- butyldimethylsilyl protecting group are synthesized (base moieties are adenine, guanine, thymine and 5-methylcytosine). The nucleosides are obtained by ring opening reaction of 1,5:2,3-dianhydro-4,6-O-benzylid

D-Altritol nucleosides with an adenine and uracil base moiety were obtained by nucleophilic opening of the epoxide ring of 1,5:2,3-dianhydro- 4,6-O-benzylidene-D-allitol using the sodium salt of the above mentioned bases. The use of a 2-trimethylsilylethyl protecting group for the O6- function of the guanine base offers a useful compromise between stability and acceptable alkylation yields of the N9-position if the guanine base. The cytosine nucleoside was synthesized starting from the uracil congener. The 3'-hydroxyl function was protected with a benzoyl group.
