SYNTHESIS OF 5-METHYLAMINO-2′-DEOXYURIDINE DERIVATIVES |
| |
Abstract: | Reductive amination of 3′,5′-O-(tetraisopropyldisilyloxane-1,3-diyl)-2′-deoxy-5-formyluridine with several aliphatic and aromatic amines, in various solvents, is described. In the case of aliphatic amines, the expected C-5 substituted methylamino pyrimidine nucleosides are formed along with by-products deriving from opening of the pyrimidine ring. Relative amounts of the by-products depend upon the polarity of the solvent employed. |
