method for the chemical synthesis of oligoribonucleotides containing 2'-O-phosphate at a selected position is presented. Synthesis of these oligoribonucleotides is based on uridine- and adenosine-(2'-O-phosphate)-3'-phosphoramidites, and a new condition for removal of 2'-O-phosphate protecting groups, which does not cleave internucleotide bonds. The structure of oligoribonucleotides with 2'-O-phosphate
提出了一种亚磷酰胺固相支持物方法,用于化学合成在选定位置含有2'-O-磷酸的寡核糖核苷酸。这些寡核糖核苷酸的合成是基于尿苷-和腺苷-(2'-O-磷酸)-3'-亚磷酰胺,以及去除2'-O-磷酸保护基团的新条件,该条件不能裂解核苷酸间键。具有2'-O-磷酸的寡核糖核苷酸的结构已通过酵母2'-磷酸转移酶的酶促消化和去磷酸化得到证实。
