  Novel 5-HT3 antagonists: indol-3-ylspiro(azabicycloalkane-3,5'(4'H)oxazoles)

  摘要：

  The synthesis and biochemical evaluation of a series of spirofused indole oxazoline 5-HT3 antagonists is described in which the oxazoline ring acts as a bioisosteric replacement for esters and amides. The effect of substitution about the indole ring has shown the steric limitations of the aromatic binding site. Incorporation of a variety of azabicyclic systems within the rigid spirofused framework has allowed the definition of a binding model which incorporates a number of known antagonists and agonists. In this model steric constraints limit substitution around the indole ring although there is some bulk tolerance at the 1- and 2-positions. The importance of constraining the basic nitrogen within an azabicyclic system is underlined by comparison with the monocyclic piperidine. The highest affinity was observed for those compounds in which the basic nitrogen occupies a bridgehead position, the most potent analogue in this group being the azabicyclic [3.3.1] system (pIC50 = 8.95), suggesting lipophilic interactions may play a role in increasing affinity. A suggested model for agonist binding is included in which the basic nitrogens are superimposed and the 5-hydroxyl group of 5-HT is superimposed on the H-bond-accepting atom of the heterocyclic linking group.

  A combination of LiO‐tBu, CsF, and 18‐crown‐6 can be used to carboxylate indole derivatives at the C‐2 position under an ambient CO2 atmosphere. Substrates bearing an electrophilic substituent (i.e. CN, formyl, benzoyl, phenylsulfonyl, phenylsulfinyl, and chloride) at the C‐3 position are smoothly converted into their corresponding carboxylated products with high functional group compatibility.

  LiO-的组合吨卜，CsF和18-冠-6可用于羧酸盐的环境CO下在C-2位的吲哚衍生物2的气氛。在C-3位置带有亲电取代基（例如CN，甲酰基，苯甲酰基，苯磺酰基，苯亚磺酰基和氯化物）的底物可以平滑地转化为具有高官能团相容性的相应羧化产物。
