Conformationally restricted analogues of SPD-304, the first small-molecule TNFα inhibitor, in which two heteroaryl groups, indole and chromone, are connected by chiral methyl- or ethyl-cis-cyclopropane, were designed. Synthesis of these molecules was achieved via Suzuki–Miyaura or Stille coupling reactions with chiral bromomethylenecyclopropane or iodovinyl-cis-cyclopropane as the substrate, both of
设计了第一个小分子TNFα抑制剂SPD-304的构象受限类似物,其中两个杂芳基(吲哚和色酮)通过手性甲基或乙基-顺式-环丙烷连接。这些分子的合成是通过以手性溴亚甲基环丙烷或碘乙烯基-顺-环丙烷为底物的Suzuki-Miyaura或Stille偶联反应实现的,两者均由手性亚甲基环丙烷作为常见中间体制备,构建了杂芳基-甲基或-乙基-顺式-环丙烷结构是关键步骤。这项研究提出了具有两个杂芳基的一系列手性顺式-环丙烷共轭物的有效合成。
