3-Spiropseudonucleosides, in which the heterocyclic base is a five-membered (oxazolidine, imidazolidine, thiohydantoin) or six-membered (perhydrooxazine) heterocycle, have been prepared starting from a hexofuranos-3-ulose. The method leads to good yields and is completely stereoselective. The key intermediate is a sugar iso(thio)cyanate.
已经从六呋喃糖-3-基糖开始制备了3-螺伪假核苷,其中杂环碱基是五元(恶唑烷,咪唑烷,硫代乙内酰脲)或六元(全氢恶嗪)杂环。该方法产生了良好的产率,并且是完全立体选择性的。关键中间体是糖异(硫)氰酸酯。
