阅读说明：本技术 官能化的双环呋喃及其合成 (Functionalized bicyclic furans and synthesis thereof ) 是由 K·坎德尔 S·T·科恩 M·塞尔希克欧利 C·C·H·阿蒂恩扎 A·A·盖尔乌斯卡 于 2019-02-11 设计创作，主要内容包括：一种5,5’-二-(保护的)-2,2’-双环呋喃：其中每个R<Sup>1</Sup>独立地是未取代的或者取代的5-或者6-元1,3-二氧代-2-基环基团。制造所述双环呋喃的方法包括偶联2-(保护的)-糠醛。使用所述双环呋喃的方法包括脱保护、官能化和/或聚合来形成聚酯。该聚酯可以是可再生的高性能聚酯,其提供了低生产成本、高持续性和优异性能的组合。(A5, 5 '-bis- (protected) -2, 2' -bicyclic furan: wherein each R 1 Independently an unsubstituted or substituted 5-or 6-membered 1, 3-dioxo-2-yl ring group. A method of making the bicyclic furans includes coupling 2- (protected) -furfural. Methods of using the bicyclic furans include deprotection, functionalization, and/or polymerization to form polyesters. The polyester may be a renewable high performance polyester that provides a combination of low production cost, high sustainability, and excellent performance.)
