An efficient approach to hydroxylated pyrrolidine and piperidine derivatives through the intramolecular hydroamination catalyzed by a Cu(I)-Xantphos system is described. The transformation allows for the short synthesis of N-alkylated aza-sugars without a protection-deprotection event of the hydroxy groups.
描述了通过由 Cu(I)-Xantphos 系统催化的分子内加氢胺化作用来制备羟基化吡咯烷和哌啶衍生物的有效方法。该转化允许在没有羟基的保护-脱保护事件的情况下短时间合成 N-烷基化氮杂糖。
