  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.

• Electrophilicity and nucleophilicity of commonly used aldehydes

  日期：——

  The present approach for determining the electrophilicity (E) and nucleophilicity (N) of aldehydes includes a kinetic study of KMNO4 oxidation and NaBH4 reduction of aldehydes. A transition state analysis of the KMNO4 promoted aldehyde oxidation reaction has been performed, which shows a very good correlation with experimental results. The validity of the experimental method has been tested using the experimental activation parameters of the two reactions. The utility of the present approach is further demonstrated by the theoretical versus experimental relationship, which provides easy access to E and N values for various aldehydes and offers an at-a-glance assessment of the chemical reactivity of aldehydes in various reactions.

  目前用于确定醛类电亲和性(E)和核亲和性(N)的方法包括对KMNO4氧化和NaBH4还原醛类的动力学研究。对KMNO4促进的醛氧化反应的过渡态分析表明，其与实验结果具有非常好的相关性。通过两种反应的实验活化参数验证了实验方法的有效性。通过理论与实验关系的进一步证明，该方法为各种醛类提供了便捷获取E和N值的途径，并能直观评估醛类在不同反应中的化学反应性。
