We have developed a simple method for the deprotection of allyl groups used as a protective group for the anomeric oxygen on a sugar moiety by employing tetrakis(triphenylphosphine) palladium in acetic acid. This method is applicable for not only simple but also complex allyl glycosides, such as natural lipid A intermediates and other important lipid A intermediates. Further, this method would be useful for large-scale preparation.

钯,对用作糖部分上异头氧的保护基的烯丙基进行脱保护。该方法不仅适用于简单的烯丙基糖苷,也适用于复杂的烯丙基糖苷,例如天然脂质A中间体和其他重要的脂质A中间体。此外,该方法可用于大规模制备。
