Hb. Lazrek et al., SYNTHESIS OF 3'-DEOXY-3' AND 5'-DEOXY-5'-[4-(PURIN-9-YL PYRIMIDIN-1-YL)METHYL-1,2,3-TRIAZOL-1-YL]THYMIDINE VIA 1,3-DIPOLAR CYCLOADDITION/, Nucleosides & nucleotides, 16(7-9), 1997, pp. 1073-1077
Synthesis of new 3'-deoxy-3' and xy-5'-[(4-(purin-9-yl/pyrimidin-1-yl)
methyl-1,2,3- 8a-g, 10a-g from 3'-azido-3'-deoxy-5'-O-monomethoxytrity
l-thymidine and 5'-azido-5'-deoxythymidine respectively are described.
The key step is the 1,3-dipolar cycloaddition between the azido group
and N-9/N-1-propargylpurine/pyrimidine derivatives.
