    Development of a Scalable Process for α-Amino-ω-methoxyl-dodecaethylene Glycol
    摘要:
    We have developed a process for the efficient and scalable preparation of heterofunctionalized dodecaethylene glycol from the readily available tetraethylene glycol and its macrocyclic sulfate. By employing the benzyl group as both a protecting group and a separative tag, multiple chromatographic separations were avoided. With this method, alpha-amino-omega-methyl-dodecaethylene glycol was prepared on a 53 g scale with high purity and 61% overall yield in eight steps and one chromatographic separation.

  • Highly Efficient Synthesis of Monodisperse Poly(ethylene glycols) and Derivatives through Macrocyclization of Oligo(ethylene glycols)
    作者:Hua Zhang、Xuefei Li、Qiuyan Shi、Yu Li、Guiquan Xia、Long Chen、Zhigang Yang、Zhong-Xing Jiang

    日期:2015.3.16
    A macrocyclic sulfate (MCS)‐based approach to monodisperse poly(ethylene glycols) (M‐PEGs) and their monofunctionalized derivatives has been developed. Macrocyclization of oligo(ethylene glycols) (OEGs) provides MCS (up to a 62‐membered macrocycle) as versatile precursors for a range of monofunctionalized M‐PEGs. Through iterative nucleophilic ring‐opening reactions of MCS without performing group
    已开发出一种基于大环硫酸盐(MCS)的单分散聚乙二醇(M-PEG)及其单官能化衍生物的方法。寡聚乙二醇(OEG)的大环化提供了MCS(最多62个成员的大环),作为一系列单官能化M-PEG的通用前体。通过MCS的反复亲核开环反应而无需进行基团保护和激活,可以轻松制备一系列M-PEG,包括史无前例的64-mer(2850 Da)。合成简单性与这种新策略的多功能性可能为M-PEG的更广泛应用铺平道路。
