  Gold(I)-Catalyzed Cascade Approach for the Synthesis of Tryptamine-Based Polycyclic Privileged Scaffolds as α₁-Adrenergic Receptor Antagonists

  摘要：

  An efficient and facile gold(I)-catalyzed one-pot cascade protocol has been developed for the synthesis of tryptamine-fused polycyclic privileged structures through the treatment of substituted tryptamines and 2-ethynylbenzoic acids or 2-ethynylphenylacetic acids. This strategy features the formation of one C-C bond and two C-N bonds with high yields and broad substrate tolerance. The selected reduced target molecules are validated to perform as alpha(1)-adrenergic receptors antagonists. The most potent one, 4bh, exhibits an IC50 value of 277 nM on alpha(1A) subtype with a selectivity ratio of 15.8 over alpha(1B) subtype.
