    Mechanistic Study of Glycosylation Using a Prop-1-enyl Donor
    摘要:
    Studies have been conducted to elucidate the mechanism of glycosylation reactions using a prop-1-enyl donor isomerized directly from an allyl glycoside. The reactions promoted by NIS/TfOH can take place in high yields in acetonitrile at room temperature. Activation of the anomeric prop-1-enyl group often leads to both the desired glycoside (e.g., 9) and the addition-reaction product (e.g., the anomeric mixed acetal 10). TfOH perhaps has a dual role in the reaction: i.e., (a) producing IOTf in situ to activate the prop-1-enyl group and (b) catalyzing the transformation from the addition-reaction product to the desired glycoside (e.g., from 10 to 9). The latter process involves multiple competing pathways.

  • Glycosyl iodides are highly efficient donors under neutral conditions
    作者:Michael J. Hadd、Jacquelyn Gervay

    日期:1999.7
    Abstract Glycosyl iodides have been prepared and subjected to glycosylation under neutral conditions. The reactions are highly efficient, giving α glycosides even with sterically demanding glycosyl acceptors. Glucosyl iodides react with allyl alcohol slowest and require refluxing conditions. Galactosyl iodides are intermediate in reactivity, providing the allyl glycoside in 3 h at room temperature
    摘要制备了糖基碘化物并在中性条件下进行糖基化。该反应是高效的,即使具有空间上要求的糖基受体也能得到α糖苷。葡萄糖基碘与烯丙醇的反应最慢,需要回流条件。半乳糖基碘化物是反应性的中间产物,在室温下3小时内可提供烯丙基糖苷,而岩藻糖基碘化物的糖基化在相似条件下可在不到1小时内发生。用包括异头羟基在内的各种受体证明了反应的范围和局限性,得到了海藻糖类似物。在不存在C-2参与的情况下,只需将溶剂从苯改成乙腈就可以实现葡萄糖基碘化物的β-选择性糖基化。

    The reaction of tetra-O-benzylmannosyl trichloroacet­imidate with electron-rich phenols in the presence of TMSOTf surprisingly leads to the exclusive formation of aryl β-C-glycosides while a preference for the α-anomer could be observed with other Lewis acids such as ZnCl2.

    A range of mono- and disaccharides, including glucose derivative 10, has been cleanly coupled, in the presence of a Pd catalyst, with various halogenated and structurally distinctive tropones, including “parent” compound 11, to afford the corresponding α- and β-anomeric forms of the tropolone glycosides, e.g., 12 and 13, respectively. Varying the ligand used influences the anomer distribution significantly

    to excellent yields with high levels of stereoselectivity. Useful C3-unit elongation, which makes the best use of an allyl ether as a protecting group and a nucleophilic allylation agent, is demonstrated. Mechanisms for the umpolung reaction (of an allyl ether into an allylic anion) and stereoselectivity associated with allylation of aldehydes are discussed.
