  SmI 2促进的与N-（2-吲哚基）恶唑烷酮的自由基加成反应：双吲哚化合物的合成

  摘要：

  在-78°C下用二碘化sa处理吲哚环的取代模式不同的N-苄基2-吲哚羧酸的N-酰基恶唑烷酮导致形成两个吲哚二聚体产物。分离出的主要产物的产率为55-59％，其代表不对称的二聚体，该不对称的二聚体是由于N的外环羰基还原引起的可能的酮基型自由基阴离子中间体的2-4-吲哚羧酸衍生物的加成而产生的。-酰基恶唑烷酮。以对称二酮为代表的次要二聚体的产率为11％至23％。即使存在α，β-不饱和酰胺，二聚化也是优选的途径，而不是γ-酮酰胺的形成。用酸处理后，不对称的吲哚二聚体环化形成二吲哚醌。最后，在两种情况下，吡咯-2-羧酸和3-吲哚羧酸的N-酰基恶唑烷酮优选在SmI 2的存在下与丙烯酰胺进行CC键形成而不是二聚化。

  Design and Synthesis of Novel Indole β-Diketo Acid Derivatives as HIV-1 Integrase Inhibitors

  摘要：

  Diketo acids such as S-1360 (1A) and L-731,988 (2) are potent and selective inhibitors of HIV-1 integrase (IN). A plethora of diketo acid-containing compounds have been claimed in patent literature without disclosing much biological activities and synthetic details (reviewed in Neamati, N. Exp. Opin. Ther. Pat. 2002, 12, 709-724). To establish a coherent structure-activity relationship among the substituted indole nucleus bearing a beta-diketo acid moiety, a series of substituted indole-beta-diketo acids (4a-f and 5a-e) were synthesized. All compounds tested showed anti-IN activity at low micromolar concentrations with varied selectivity against the strand transfer process. Three compounds, the indole-3-beta-diketo acids 5a and 5c, and the parent ester 9c, have shown an antiviral activity in cell-based assays. We further confirmed a keto-enolic structure in the 2,3-position of the diketo acid moiety of a representative compound (4c) using NMR and X-ray crystallographic analysis. Using this structure as a lead for all of our computational studies, we found that the title compounds extensively interact with the essential amino acids on the active site of IN.
