furanose diol as the key step in the synthesis of a novel bicyclo 3-amino-3-deoxy furanose derivative, which is an important intermediate for the synthesis of bicyclic analogs of AZT. The asymmetrization of the diol has been achieved with preferred formation of a monoacylated product with 100% diastereoselectivity. An efficient synthesis of an intermediate in the synthesis of amino derivatized bicyclonucleosides
已经证明了南极假丝酵母脂肪酶的选择性,并将其用于非对位呋喃糖二醇的合成中,这是合成新型双环3-氨基-3-脱氧呋喃糖衍生物的关键步骤,这是合成双环的重要中间体AZT的类似物。通过优选形成具有100%非对映选择性的单酰化产物已经实现了二醇的不对称。还描述了在氨基衍生的双环核苷的合成中中间体的有效合成,已经制备了两种这样的含有环氨基残基的新型化合物。
