  • TMSOTf-Catalyzed Silylation: Streamlined Regioselective One-Pot Protection and Acetylation of Carbohydrates
    作者:A. Abragam Joseph、Ved Prakash Verma、Xin-Yi Liu、Chia-Hui Wu、Vijay M. Dhurandhare、Cheng-Chung Wang

  • Toward an Improved Triterpene 3-<i>O</i>-Glucuronidation: The Systematic Determination of the Relative Reactivities of Glucuronyl Donors and Acceptors
    作者:Yen-Hsun Lai、Yu-Ting Chou、You-Yu Lin、Yi-Chi Wang、Jing-Xiu Cao、Pi-Hui Liang
    DOI:10.1021/acs.joc.3c00709
    日期:2023.7.21
    oleanane-type triterpene acceptors were synthesized, and the relative reactivity values (RRV) and acceptor nucleophilic constants (Aka) were systematically measured to study their influence on glucuronidation yield. As a result, applying donors in higher RRV value generally improved the production of 3-O-glucuronide triterpenes. Meanwhile, a bulky pivaloyl group was an ideal 2-O-protection to provide β-selectivity
    3- O -β-葡萄糖醛酸三萜是源自植物的化合物。其中一些已被用作草药和药物,例如竹节皂苷和皂树皂苷。然而,由于这些材料的天然稀缺性和低产率的纯化过程,对这些材料的需求在很大程度上仍然是一个挑战。因此,本研究进行了化学三萜3- O-葡萄糖醛酸化,以缓解对天然来源不断增长的需求。合成了各种葡萄糖酰亚胺酯供体和齐墩果烷型三萜受体,并系统测量了相对反应性值(RRV)和受体亲核常数(Aka),研究了它们对葡萄糖醛酸化产率的影响。因此,应用较高 RRV 值的供体通常会提高 3- O-葡萄糖醛酸苷三萜的产量。同时,庞大的新戊酰基是理想的 2- O-保护,可提供 β-选择性并防止副反应,包括原酸酯形成和酰基转移反应。总的来说,反应性供体/受体与提高的葡萄糖醛酸化产率之间观察到正相关。这些发现提供了关于供体和受体反应性对 3- O -β-葡萄糖醛酸三萜合成的影响的见解,这些知识将有助于获取感兴趣的皂苷以满足未来的需求。
