  通过闭环易位脱对称化合成唾液酸。

  摘要：

  天然的脱氨基唾液酸KDN（2）（一种潜在的胎粪抗原）和N-乙酰神经氨酸（Neu5Ac，1）（一种最天然的唾液酸）的形式总合成已经完成，总收率达到46％和9.3％，分别通过新颖的缩酮化/闭环复分解序列。以完全立体控制的方式快速引入所有氧和氮官能团，利用了刚性的6,8-二氧杂双环[3.2.1]辛-2-烯模板。2，7-脱水-KDN衍生物40在两种合成中均用作高级中间体。

  Benzotriazole-Mediated Conversions of Aromatic and Heteroaromatic Aldehydes to Functionalized Ketones

  摘要：

  Aromatic and heteroaromatic aldehydes reacted with benzotriazole and triethyl orthoformate in THF to give the corresponding alpha-(benzotriazol-1-yl)aryl ethyl ethers 7 in good yield. The novel acyl anion precursors 7 underwent smooth lithiation at the methine group followed by trapping with alkyl halides, aldehydes, ketones, and imines to yield the expected substituted intermediates of type 9, which were hydrolyzed under mild conditions without isolation. Benzaldehyde, methyl-, chloro-, and methoxy-substituted benzaldehydes, 1-naphthalenecarboxaldehyde, 2- and 3-furaldehydes, 2- and 3-thiophenecarboxaldehydes, and 2-pyridinecarboxaldehyde were all transformed in this manner into a variety of aryl and heteroaryl ketones with alkyl (10), alpha-hydroxyalkyl (12 and 13), alpha-aminoalkyl (14) and acyl(15) substituents.

  A series of 5,6,7,8,9,10-hexahydro-7,10-iminocyclohept[b]indoles and 6,7,8,9,10,11-hexahydro-7,-11-imino-5H-cyclooct[b]indoles was prepared. Structural modifications of the lead compound, 11-[4-(4-fluorobenzoyl)propyl]-5,6,7,8,9,10-hexahydro-7,10-iminocyclohept[b]indole (5, K(i) = 0.82 nM vs [H-3]ketanserin) enabled the identification of the functionality necessary for high affinity at serotonin 5-HT2 and dopamine D2 receptors in ligand binding studies. The indole ring, as well as the benzoyl or isosteric benzisoxazole moiety, were essential for high affinity. Variations of the length of the side chains resulted in ligands having either selective affinity for the 5-HT2 receptor or a combination of 5-HT2 and D2 affinity. In vivo binding studies were performed on selected members in this series. The most potent member, 2-fluoro-11-[4-(4-fluorobenzoyl)butyl]-5,6,7,8,9,-10-hexahydro-7,10-iminocyclohept[b]indole (36) had an ED50 of <1 mg/kg at the 5-HT2 and D2 receptors following oral administration.
