    application of both Schmidt and Yu glycosylations, the first total syntheses of the echinocystic acid saponins pithedulosides D and E, the two antitumoral and representative D-ring-functionalized oleanane-type saponins, were achieved. Benefitting from the applied convergent synthetic strategy, the echinocystic acids could be synthesized in overall yields of as high as 71 and 76 % through four linear steps

    日期:2018.9.7
    An enol-type glycosylation reaction has been investigated. Enol glycosides can be obtained from the reaction between O-glycosyl trichloroacetimidates and the corresponding ketones promoted by an acid. The enol glycosides derived from cyclic ketones can be afforded efficiently and isolated in good yield, while those from acyclic ketones are prepared in low conversion or are too labile for isolation
    已经研究了烯醇型糖基化反应。烯醇糖苷可以从O-糖基三氯乙亚氨酸酯与相应的由酸促进的酮之间的反应中获得。可以有效地提供衍生自环状酮的烯醇糖苷并以高收率分离,而衍生自无环酮的烯醇糖苷转化率低或太不稳定而无法分离。对不同糖基供体类型的进一步研究表明,只有O-糖基三氯乙酰亚氨酸酯可以很好地用作烯醇糖基化的供体。
