2-ethylenediamine derivatives were synthesized from acetylated allyl alpha-C-glycosyl compounds via dibromination, azidation, carbohydrate deprotection, and azide reduction. Four 1,3-propanediamine derivatives were prepared from acetylated sugar halides via C-glycosylation with sodiomalononitrile, followed by the reduction of the nitrile moieties and the deacetylation of the carbohydrate moiety. These
描述了实用和方便的C-糖基1,2-和1,3-烷二胺的制备方法。通过二溴化,叠氮化,碳水化合物脱保护和叠氮化物还原,由乙酰化的烯丙基α-C-糖基化合物合成了两种1,2-乙二胺衍生物。由乙酰化的卤代糖经与磺基丙二腈的C-糖基化反应,然后还原腈基部分和使碳水化合物部分脱乙酰基,制得四种1,3-丙二胺衍生物。这些1,3-丙二胺衍生物具有β-端基异构体构型。本文报道的方法用作获得具有C-糖基键的碳水化合物-二胺缀合物的一般途径。
