nitrogen hybridization guanine nucleoside and its synthetic method and the use of DNA sequencing

The invention discloses hybrid azaguanosine as well as a synthesis method and an application thereof in DNA sequencing. The synthesis method comprises the steps: removing a protecting group of a compound as shown in formula (III) in the specification under an alkaline condition to obtain a compound as shown in formula (II) in the specification; further demethylating to obtain a compound as shown in formula (I) in the specification, i.e. 7-deaza-7-halogen-8-aza-guanosine, wherein R1 is H or OH, R2 is I, Br or Cl, and R3 is H or a compound shown in the specification. The hybrid azaguanosine disclosed by the invention is a novel reagent for DNA sequencing, which, compared to guanosine failing to substitute nitrogen on 8 sites, is more excellent in base identifying effect and more stable in DNA chain structure. Meanwhile, different from the prior art that 8-site nitrogen-substituted guanosine is complex in synthesis method, low in yield and unsuitable for commercial production, the synthesis method disclosed by the invention is easily available in raw material required, and adopts conventional chemical synthesis reaction; and the method is relatively high in yield, and suitable for wide popularization and application.

Process for the synthesis of pyrazolopyrimidines

The present invention provides a nucleoside comprising a pyrazolopyrimidine base and a process for producing the same. In particular, the processes of the present invention comprises using a halogenated pyrazolopyrimidine base and removing the halogen after the base is coupled to a sugar moiety. The presence of the halogen on the nucleoside base allows facile and economical production of a large quantity of nucleosides.
