  Novel 5-HT3 antagonists. Indole oxadiazoles

  摘要：

  The synthesis and biochemical evaluation of a series of indole oxadiazole 5-HT3 antagonists are described. The key pharmacophoric elements have been defined as a basic nitrogen, a linking group capable of H-bonding interactions, and an aromatic moiety. The steric limitations of the aromatic binding site have been determined by substitution about the indole ring. Variation of the heterocyclic linking group has shown that while two hydrogen-bonding interactions are possible, only one is essential for high affinity. The environment of the basic nitrogen has been investigated and shown to be optimal when constrained within an azabicyclic system. These results have been incorporated into a proposed binding model for the 5-HT3 antagonist binding site, in which the optimum distance between the aromatic binding site and the basic amine is 8.4-8.9 angstrom and the steric limitations are defined by van der Waals difference mapping.

  水杨醛促进钴催化 C-H/N-H 环化吲哚酰胺与炔烃：直接合成 5-HT3 受体拮抗剂类似物

  摘要：

  据报道，在 8-氨基喹啉的辅助下，吲哚酰胺的 C(sp 2 )-H/N-H 键与炔烃的钴催化环化可用于合成六元吲哚内酰胺。使用水杨醛作为配体对于这种转化至关重要。该协议对炔烃和吲哚都有广泛的适用范围。制备活性 Co 复合物说明水杨醛在 C-H 活化步骤中起关键作用。合成应用通过多环 5-HT3 受体拮抗剂的克级反应和一步构建得到证实。

  A nickel-catalyzed, enantioselective, three-component fluoroalkylarylation of unactivated alkenes with aryl halides and perfluoroalkyl iodides has been described. This cross-electrophile coupling protocol utilizes a chiral nickel/BiOx system as well as a pendant chelating group to facilitate the challenging three-component, asymmetric difunctionalization of unactivated alkenes, providing direct access
