  The Role of the C-3 Substituent in the Asymmetric Dihydroxylation of Hexo-5-Enofuranosides

  摘要：

  Asymmetric dihydroxylation of vinyl furanosides 1-6 by use of OsO4, ADmix-alpha (R) and beta (R) is described yielding the corresponding hexofuranose sugars. Vinyl furanosides 2 and 3, with an eater group at C-3, and vinyl manno furanoside 5 on asymmetric dihydroxylation with AD-mix alpha (R) exhibited high R diastereoselectivity at C-5. Reversal in diastereoselectivity at C-5 was observed for the 3-deoxy vinyl furanoside 6 giving furanosaccharide 6S with the S configuration at C-5.

  partial O -deacylation of fully acylated methyl glycosides and some other glycosyl compounds (23 compounds) was found to be induced, to give, in good yields, products bearing one free hydroxyl group; the results obtained indicated that, among the primary and secondary O -acyl groups, the 2- O -acyl groups were, in general, the most labile toward the nucleophile (hydrazine). Hydrazinolysis of 1,2- O -

  摘要在1：4乙酸-吡啶中进行肼解后，在吡啶中，可诱导完全酰化的甲基糖苷和某些其他糖基化合物（23种化合物）的部分O-脱酰作用，从而以较高的收率得到含1种化合物的产物。游离羟基 所得结果表明，在伯和仲O-酰基中，2-O-酰基通常对亲核试剂（肼）最不稳定。另一方面，对1，2-O-异亚丙基戊二醛呋喃糖酰化物（3种化合物）进行水合肼解，以高收率得到相应的在其伯羟基上具有保护基的单酰基衍生物。讨论了可能与肼解的区域选择性有关的因素。

  Bi(OTf)(3)-catalyzed acylation of alcohols with acid anhydride was evaluated in comparison with other acylation methods. The Bi(OTf)(3)/acid anhydride protocol was so powerful that sterically demanding or tertiary alcohols could be acylated smoothly. Less reactive acylation reagents such as benzoic and pivalic anhydride are also activated by this catalysis. In these cases, a new technology was developed

  与其他酰化方法相比，评估了Bi（OTf）（3）催化的酸酐与酸酐的酰化反应。Bi（OTf）（3）/酸酐操作规程如此强大，以至于空间需求量高的或叔醇都可以被平滑地酰化。反应性较低的酰化试剂，例如苯甲酸酯和新戊酸酐，也可以通过这种催化活化。在这些情况下，为了克服将酰化产物与剩余的酰化试剂分离的困难，开发了一种新技术：未反应的酸酐的甲醇化成易于分离的甲酯实现了所需酰化产物的非常容易的分离。Bi（OTf）（3）/酸酐方案适用于具有各种功能的多种醇。酸不稳定的THP或TBS保护的醇，糠醇，香叶醇和碱不稳定的醇也可以被酰化。在室温下甚至进行官能化叔醇的酰化。

  protocol does not require the addition of any base or activator. This methodology has been further extended to the selective acylation of carbohydrate diols and the one-pot preparation of acetylated glycosyl chlorides direct from free reducing sugars. The yields obtained in most of the cases are excellent.

  The transformation of acetonides into the corresponding diacetates is often required in the synthetic chemistry. An efficient procedure for direct conversion of acetonides into diacetates in the presence of Bi(OTf)3·xH2O under mild conditions has been developed. Primary hydroxyl-acetonides could be selectively transformed into diacetates in the presence of anomeric acetonides and the anomeric acetonides
