  一种贝前列素钠中间体的合成方法

  摘要：

  本发明涉及一种贝前列素钠中间体III的合成方法。以环戊烯和N‑溴代丁二酰亚胺(NBS)通过自由基反应得到二溴环戊烯，二溴环戊烯与2,4,6‑三溴苯酚相互作用直接以“一锅煮”法直接形成3,5‑双(2,4,6‑三溴苯氧基)环戊烯(化合物I)。再通过格氏反应得到化合物II和化合物III。且本发明采用N‑溴代丁二酰亚胺和商业化可获得的环戊烯为原料合成二溴环戊烯，避免了170℃裂解和‑30～‑40℃的超低温反应，同时避免了溴素的使用；反应条件更温和、环境更友好，便于工业化生产。

  compounds constitute rather rare examples of supramolecular isomerism. The thermogravimetric analyses of the inclusion compounds show that the guest in one of the modifications is released in a relatively higher temperature range. The structural diversity exhibited by the host TP with various guest molecules and its ability to exhibit different forms with the same guest has been to attributed its unique

• Designing Degradable Polymers from Tricycloalkenes via Complete Cascade Metathesis Polymerization

  Cascade metathesis polymerization has been developed as a promising method to synthesize complex but well‐defined polymers from monomers containing multiple reactive functional groups. However, this approach has been limited to the monomers involving simple alkene/alkyne moieties or produced mainly non‐degradable polymers. In this study, we demonstrate a complete cascade ring‐opening/ring‐closing metathesis polymerization (RORCMP) using various tricycloalkenes and two strategies for the efficient degradation. Through rational design of tricycloalkene monomers, the structure and reactivity relationship was explored. For example, tricycloalkenes with trans configuration in the central ring enabled faster and better selective cascade RORCMP than the corresponding cis isomers. Also, a 4‐substituted cyclopentene moiety in the monomers significantly enhanced the overall cascade RORCMP performance, with the maximum turnover number (TON) reaching almost 10,000 and molecular weight up to 170 kg/mol using an amide‐containing monomer. Furthermore, we achieved one‐shot cascade multiple olefin metathesis polymerization using tricycloalkenes and a diacrylate, to produce new highly A,B‐alternating copolymers with full degradability. Lastly, we successfully designed xylose‐based tricycloalkenes to give well‐defined polymers that underwent ultra‐fast and complete degradation under mild conditions.
