Opening of 2',3'-O-anhydro-ring of 2',3'-O-anhydro-lyxo-uridine by alkyl- and arylamines. Easy syntheses and preparative uses of 2'-deoxy-2'-alkylamino-xylo- and 3'-deoxy-3'-alkylamino-ara-uridines

Contrary to the previous report (ref. 8), under controlled conditions alkylamines, both primary and secondary and arylamines, opened the epoxide ring of 1-(5-O-trityl-2,3-O-anhydro-β-D-lyxo-furanosyl)-uracil to produce 2'-deoxy-2'-alkylamino-xylo- and 3'-deoxy-3'-alkylamino-ara-uridines without causing any significant deglycosylation. To show the utility of these products, several modified uridine derivatives
与先前的报告(参考文献8)相反,在受控条件下,伯胺,仲胺和芳基胺均烷基胺打开了1-(5-O-trityl-2,3-O-anhydro-β-D-lyxo的环氧环-呋喃糖基)-尿嘧啶,以产生2'-脱氧-2'-烷基氨基-木糖基和3'-脱氧-3'-烷基氨基-阿拉伯-尿苷,而不会引起任何显着的去糖基化。为了显示这些产品的实用性,合成了几种修饰的尿苷衍生物。
