  The present invention relates to dideoxynucleoside derivatives useful as antiviral agents, intermediates useful for synthesizing them and synthetic processes thereof. The processes of the present invention are characterized in that a mesyl group, a tosyl group or a trifluoromethanesulfonyl group is selectively introduced into the ribose 3'-position of the various nucleoside derivatives in which the base component, the ribose 2'-position, and 5'- position are protected and then treated with a base and a reducing agent to produce effectively intermediates useful for synthesizing dideoxynucleoside derivatives. By employing this process, various novel intermediadtes and dideoxynucleoside derivatives can be obtained. Further, the present invention provides the process for synthesizing the intermediates useful for synthesizing dideoxynucleoside derivatives, which comprises reacting an alkaline compound with nucleoside derivatives in which the base component, the ribose 2'-position and the ribose 5'-position are protected with pivaloyl groups and the ribose 3'-position is protected with a mesyl group, a tosyl group or a trifluoromethanesulfonyl group to selectively eliminate only the pivaloyl group of the base to thereby produce the intermediate.

  本发明涉及用作抗病毒剂的二脱氧核苷衍生物、用于合成它们的中间体及其合成工艺。 本发明工艺的特点是，在碱基成分、核糖 2'- 位和 5'- 位受到保护的各种核苷衍生物的核糖 3'- 位上，选择性地引入一个甲磺酰基、一个甲苯磺酰基或一个三氟甲磺酰基，然后用碱和还原剂处理，从而有效地生成用于合成双脱氧核苷衍生物的中间体。采用这种工艺可以获得各种新型中间体和二脱氧核苷衍生物。 此外，本发明还提供了用于合成二脱氧核苷衍生物的中间体的合成工艺，该工艺包括将碱性化合物与核苷衍生物反应，其中碱基成分、核糖 2'- 位和核糖 5'- 位被新戊酰基保护，核糖 3'- 位被甲磺酰基、甲苯磺酰基或三氟甲磺酰基保护，以选择性地只消除碱基的新戊酰基，从而生成中间体。
