  摘要：

  The chemical synthesis of isoxanthopterin and 6-phenylisoxanthopterin N-8-(2'-deoxy-beta -D-ribofuranosyl nucleosides) is described as well as their conversion into suitably protected 3'-phosphoramidite building blocks to be used as marker molecules for DNA synthesis. Applying the npe/npeoc (=2-(4-nitrophenyl)ethyl/[2-(4-nitrophenyl)ethoxy]carbonyl) strategy, we used the new building blocks in the preparation of oligonucleotides by an automated solid-support approach, The hybridization properties of a series of labelled oligomers were studied by UV-melting techniques. It was found that the newly synthesized markers only slightly interfered with the abilities of the labelled oligomers to form stable duplexes with complementary oligonucleotides.

  We have synthesized isoxanthopterin and 6-phenylisoxanthopterin nucleosides in form of their 5'-O-dimethoxytritylated 3'-phosphoramidites to be used as fluorescence markers directly in the synthesis of oligonucleotides by a machine-aided solid-support approach. The preparation of the monomers and some results of the oligonucleotide synthesis will be described.
