Popis: | 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). ispartof: JOURNAL OF ORGANIC CHEMISTRY vol:83 issue:24 pages:15155-15169 ispartof: location:United States status: published |
