  Benzoxazole Derivatives as Novel 5-HT₃ Receptor Partial Agonists in the Gut

  摘要：

  A series of benzoxazoles with a nitrogen-containing heterocyclic substituent at the 2-position was prepared and evaluated for 5-HT3 partial agonist activity on isolated guinea pig ileum. The nature of the substituent at the 5-position of the benzoxazole ring affected the potency for the 5-HT3 receptor, and the 5-chloro derivatives showed increased potency and lowered intrinsic activity. 5-Chloro-7-methyl-2-(4-methyl-1-homopiperazinyl)benzoxazole (6v) exhibited a high binding affinity in the same range as that of the 5-HT3 antagonist granisetron, and its intrinsic activity was 12% of that of 5-HT. Compound 6v inhibited 5-HT-evoked diarrhea but did not prolong the transition time of glass beads in the normal distal colon even at a dose of 100 times the ED50 for diarrhea inhibition in mice. Compounds of this type are expected to be effective for the treatment of irritable bowel syndrome without the side effect of constipation.

  ambient reaction conditions with high enantioselectivity. The close relationship of the products with well-studied o-quinols provides numerous avenues for synthetic elaboration and exciting opportunities for bioisosteric replacement of hydroxyl with fluorine in natural products.

  手性阴离子相转移催化使由 BINOL 衍生的磷酸盐催化的苯酚直接和高度对映选择性氟化脱芳构化成为可能。该过程在环境反应条件下以高对映选择性有效地将简单、容易获得的酚类转化为带有反应性官能团的氟化手性小分子。产品与经过充分研究的邻羟基喹啉的密切关系为合成加工提供了许多途径，并为天然产物中的氟生物等排置换羟基提供了令人兴奋的机会。

  The discovery of distinct modes of asymmetric catalysis has the potential to rapidly advance chemists' ability to build enantioenriched molecules. As an example, the use of chiral cation salts as phase-transfer catalysts for anionic reagents has enabled a vast set of enantioselective transformations. A largely overlooked analogous mechanism wherein a chiral anionic catalyst brings a cationic species into solution is itself a powerful method. The concept is broadly applicable to a number of different reaction pathways, including to the enantioselective fluorocyclization of olefins, and dearomatization of aromatic systems with a cationic electrophile-transferring (e.g., fluorinating) agent and a chiral phosphate catalyst. The reactions proceed in high yield and stereoselectivity. The compounds and methods of the invention are of particular value, especially considering the scarcity of alternative approaches.

  发现不对称催化的不同模式具有潜力快速推动化学家构建手性富集分子的能力。例如，使用手性阳离子盐作为相转移催化剂用于阴离子试剂已经实现了大量手性选择性转化。一个被大多数人忽视的类似机制是手性阴离子催化剂将阳离子物种溶解到溶液中，这本身就是一种强大的方法。这一概念广泛适用于许多不同的反应途径，包括对烯烃进行手性选择性氟环化和用阳离子亲电试剂转移（例如，氟化）剂和手性磷酸盐催化剂进行芳香系统去芳构化。这些反应产率高，立体选择性好。该发明的化合物和方法具有特殊价值，尤其考虑到替代方法的稀缺性。
