  • Synthesis of polyanhydrides. III.<sup>1</sup> Polyanhydrides of five‐membered heterocyclic dibasic acids<sup>2</sup>
    作者:Naoya Yoda

    Abstract

    During the course of study on the synthesis of polyanhydrides from aromatic and aliphatic dibasic acids, various types of five‐membered heterocyclic polyanhydrides was investigated. As starting materials the five‐membered heterocyclic dibasic acids, furan‐2,5‐di‐β‐propionic acid, tetrahydrofuran‐2,5‐di‐β‐propionic acid, thiophene‐2,5‐di‐β‐propionic acid, N‐methyl‐pyrrole‐2,5‐di‐β‐propionic acid and N‐methyl‐pyrrolidine‐2,5‐di‐β‐propionic acid have been prepared in high yields from readily available furfural and levulinic acid.

    Polycondensation reactions of various five‐membered heterocyclic dibasic acids were carried out with acetic anhydride at 200–300°C. under vacuum and nitrogen atmosphere. The linear heterocyclic polyanhydrides thus obtained have fiber‐ and film‐forming properties and melting points in the range of 70–190°C. It was confirmed from the experimental evidence that introduction of heterocyclic rings in the main chain of polyanhydrides decreases melting temperatures of crystallites and, hence, enhances molecular mobility, when compared with aromatic polyanhydrides previously reported3.

    The influence of the molecular structure on the physical properties of heterocyclic polyanhydrides is discussed and compared with various aromatic and aliphatic polyanhydrides. Furthermore, the polymer structure was presumed on the basis of infrared spectra and X‐ray diagrams of these polymers.

    摘要 在研究芳香族和脂肪族二元酸合成多酸酐的过程中,对各种类型的五元杂环多酸酐进行了研究。作为起始原料的五元杂环二元酸、呋喃-2,5-二-β-丙酸四氢呋喃-2,5-二-β-丙酸噻吩-2,5-二-β-丙酸N-甲基吡咯-2,5-二-β-丙酸N-甲基吡咯烷-2,5-二-β-丙酸,都是以容易获得的糠醛和左旋乙酸为原料,并以高产率制备的。各种五元杂环二元酸与乙酸酐的缩聚反应是在 200-300°C 真空和氮气环境下进行的。由此获得的线性杂环多酸酐具有纤维和成膜特性,熔点在 70-190°C 之间。实验证明,与之前报道的芳香族多酸酐相比,在多酸酐主链中引入杂环会降低晶体的熔化温度,从而提高分子的流动性3。此外,还根据这些聚合物的红外光谱和 X 射线图推测了它们的聚合物结构。

    variant is unknown. Reported herein is the first rhodium‐catalyzed asymmetric cycloisomerization of meso‐oxabicyclic alkenes tethered to bridgehead nucleophiles, thus providing access to tricyclic scaffolds through a myriad of enantioselective C−O, C−N, and C−C bond formations. Moreover, we also demonstrate a unique parallel kinetic resolution, whereby racemic oxabicycles bearing two different bridgehead
    在过去的二十年中,虽然已报道了氧杂双环烯烃与各种亲核试剂的分子间不对称开环反应引起的脱对称,但尚无分子内变异的证明。本文报道的是第一个介导桥头亲核试剂的中氧杂双环烯烃的催化的不对称环异构化反应,从而通过无数对映选择性的C-O,C-N和C-C键形成提供了进入三环骨架的途径。此外,我们还证明了独特的平行动力学分辨率,其中带有两个不同桥头亲核试剂的外消旋氧杂环可以对映选择性拆分。
