  in the oxidation of lactams moving from dimethyl dioxirane (DDO) to methyl(trifluoromethyl)dioxirane (TFDO). A physical organic chemistry study, which combines the oxidation with two other dioxiranes methyl(fluoromethyl)dioxirane, MFDO, and methyl(difluoromethyl)dioxirane, DFDO, with computational studies, points to a diverse ability of the dioxiranes to either stabilize the homo or the heterolytic

  二恶英是强大的氧化剂，可通过两种不同的机制起作用：1）均溶（H提取和氧回弹）和2）杂溶（亲电子氧化）。迄今为止，已经报道了底物的性质决定了反应模式，而与所使用的二环氧乙烷无关。在此，我们报道了前所未有的情况，其中二环氧乙烷的性质决定了氧化化学选择性。特别是，在内酰胺从二甲基二环氧乙烷（DDO）转移到甲基（三氟甲基）二环氧乙烷（TFDO）的内酰胺氧化中观察到了从CH到NH的转换。一项物理有机化学研究，将氧化与其他两种二氧杂环戊烷甲基（氟甲基）二环氧乙烷，MFDO和甲基（二氟甲基）二环氧乙烷相结合，通过计算研究，DFDO指出二恶英类化合物具有稳定同源或杂合途径的多种能力。

  Disclosed are an eight-arm polyethylene glycol (PEG) derivative (formula I), production method therefor and modified bio-related substance thereby. Wherein, one tetravalent group U together with four trivalent groups Ec form a highly symmetrical octavalent group CORE0; Lc connects the octavalent group to eight PEG chains having polydispersity or monodispersity and having n1 to n8 as the degree of polymerization thereof; the terminal of one PEG chain is connected to at least one functional group F (k≥1); said PEG chain and F therebetween can be directly connected (g=0) or be indirectly connected via a linking group L0 to a terminal end-branching group G (g=1); the latter provides more reactive sites for binding more drug molecules and increases the drug loading. The eight-arm polyethylene glycol derivative has a centrosymmetric or approximately centrosymmetric structure, and leads to more precise control of the molecular weight in large-scale production and much narrower distribution of molecular weight for products. The modified bio-related substance thereby has a more uniform and controllable performance.

  本发明公开了一种八臂聚乙二醇（PEG）衍生物（式 I）、其生产方法及其改性生物相关物质。其中，一个四价基团 U 与四个三价基团 Ec 形成一个高度对称的八价基团 CORE0；Lc 将八价基团连接到八条具有多分散性或单分散性且聚合度为 n1 至 n8 的 PEG 链上；一条 PEG 链的末端与至少一个官能团 F 连接（k≥1）；所述 PEG 链和 F 之间可以直接连接（g=0），也可以通过连接基团 L0 与末端支化基团 G 间接连接（g=1）；后者提供了更多的反应位点，可以结合更多的药物分子，增加药物负载量。八臂聚乙二醇衍生物具有中心对称或近似中心对称结构，因此在大规模生产中可以更精确地控制分子量，产品的分子量分布也更窄。因此，改性生物相关物质的性能更均匀、更可控。
