in the immune response systems. The chemical synthesis of DGDGs has been highly demanded, as it will allow the elucidation of their biological functions at the molecular level. In this study, we have developed a novel β-stereodirecting 2,3-naphthalenedimethyl (NapDM) protecting group that is orthogonal to protecting groups commonly used in oligosaccharide synthesis. The NapDM group can be easily cleaved
二糖基二酰基
甘油(DGDGs)是革兰氏阳性细菌质膜的主要成分,参与免疫应答系统。对DGDG的
化学合成提出了很高的要求,因为它将允许在分子
水平上阐明其
生物学功能。在这项研究中,我们开发了一种新型的β-立体定向2,3-
萘二甲基(Nap
DM)保护基,该保护基与
寡糖合成中常用的保护基正交。在TFA介导的酸性条件下,Nap
DM基团很容易裂解。此外,我们通过利用Nap
DM基团合成DGDG证明了该保护基在无酰基保护基策略中的应用。
