  N -2-吡啶基 idine啶和CO 2之间对吡啶并[1,2 - a ] -1,3,5-triazin-4-ones的脱芳香环化†

  摘要：

  开发了碱促进的N -2-吡啶基lam啶与大气压CO 2之间的脱芳香环化反应，提供了一系列中等至极好的吡啶并[1,2 - a ] -1,3,5-triazin-4-ones产量。CO 2用作羰基源，释放H 2 O作为纯净的副产物。而且，在该程序中不需要脱水剂和过渡金属催化剂。因此，它代表了访问此类框架的绿色，可持续和直接途径。

  The present invention discloses a 5′-amino-2′-fluoro-2′,5′-dideoxynucleoside derivative represented by the following formula [1]: (wherein R 1 represents a nucleic acid base which may have a protecting group; R 2 represents a hydrogen atom or a protecting group of an amino group; R 3 represents a hydrogen atom or a protecting group of a hydroxyl group); a dideoxynucleoside-insoluble carrier bound substance prepared by binding said dideoxynucleoside derivative to an insoluble carrier, and an oligonucleotide analogue into which said dideoxynucleoside derivative is introduced. The oligonucleotide analogue being introduced with a dideoxynucleoside derivative of the present invention has excellent thermal stability and also high binding affinity when duplex is formed. Also, it is anticipated that it has high resistance to nucleases. Further, the dideoxynucleoside derivative of the present invention can be used as an amidite reagent to be used for nucleic acid synthesis, and also as a starting material for solid phase synthesis of nucleic acid by binding the amidite reagent to a solid phase.
