    μ-Waves avoid large excesses of diisobutylaluminium-hydride (DIBAL-H) in the debenzylation of perbenzylated α-cyclodextrin
    摘要:
    Regioselective double deprotection of cyclodextrins using diisobutylaluminium-hydride (DIBAL-H) has become an important tool in functional cyclodextrin synthesis. When conventionally heated a very large excess of reagent is necessary for the reaction to happen, when mu-waves irradiation is employed the quantity of DIBAL-H can be lowered down to 5 equiv Reaction with a smaller quantity of DIBAL-H never achieved complete double debenzylation. These results also sustain the mechanistic hypothesis according to which a of two aluminium atoms are necessary for each debenzylation to occur. (C) 2009 Elsevier Ltd All rights reserved.

    摘要:
    2-卤乙基1-硫代糖苷在2-卤乙基功能被银盐或Lewis酸激活时是优秀的离去基团。这些硫代糖苷可以在原始Černý路线上合成,或者为了更复杂的糖苷合成需求与之更兼容,在通过2-(2-四氢吡喃-2-氧基)乙基糖苷或三苯基1-硫代糖苷的逐步程序中合成。糖苷化反应的初始步骤可能通过硫代环氧离子进行,这对于它们在糖苷合成中作为离去基团的反应性增加具有责任。描述了这种新系统在二糖合成中的反应性和选择性的基本特征。

    employing stable and readily accessible O-glycosyl derivatives of 2,2,6,6-tetramethylpiperidin-1-ol is presented that employs an iridium-based photocatalyst and blue LEDs. The reaction proceeds at room temperature and in the absence of additives other than 4 Å molecular sieves. Stereoselectivities are modest but nevertheless dependent on the anomeric configuration of the donor, suggesting a substantial

    Disclosed is a method for selective synthesis of 1,2-cis-α-linked glycosides which does not require the use of the specialized protecting group patterns normally employed to control diastereoselectivity. Thioglycoside acceptors can be used, permitting iterative oligosaccharide synthesis. The approach eliminates the need for lengthy syntheses of monosaccharides possessing highly specialized and unconventional protecting group patterns.

    Generally applicable and stereoselective formation of 1,2-cis-glycopyranosidic linkage remains a long sought after yet unmet goal in carbohydrate chemistry. This work advances a strategy to this challenge via stereoinversion at the anomeric position of 1,2-trans glycosyl ester donors. This SN2 glycosylation is enabled under gold catalysis by an oxazole-based directing group optimally tethered to a
