  通过碳环和亚苯乙烯缩醛的开环取代二醚二醇

  摘要：

  用硼烷或一氯硼烷还原丙二醛双（乙烯和丙烯缩醛）可以高收率生产二醚二醇1和2。乙二醛双（乙缩醛）的类似还原仅有限地用于制备四取代的三乙二醇3。有机锡化学是互补的：由二取代邻位二醇制得的亚锡乙缩醛可以与一半当量的1,2-二溴乙烷烷基化以生产四取代三乙二醇3，或与两当量的2-氯乙醇烷基化以生产二取代三乙二醇4。

  Disclosed are a multifunctionalized polyethylene glycol derivative and a preparation method therefor. The derivative has an H-shaped structure as represented by formula (1) and comprises one linear core LPEG and four PEG branch chains, where n 1 , n 2 , n 3 , and n 4 respectively are the degrees of polymerization of the branch chains, U 1 and U 2 are trivalent branching groups connecting the core LPEG to two of the PEG branch chains, F 1 and F 2 contain a functional group or a protected form R 01 thereof and may or may not contain a branched group G, correspondingly, the number of R 01 is one or more, F 1 and F 2 are either identical or different, any one linking group in the molecule or any linking group formed with an adjacent heteroatom group can either remain stable or be degraded, and any one PEG segment in the molecule is discretely polydispersed or monodispersed. The multifunctional polyethylene glycol is flexible and diverse in terms of branch structures and the lengths of branching arms, has various parameters and performance indicators that are adjustable and easy to control, and has a broad applicability.
