  Synthesis of Cytimidine through a One-Pot Copper-Mediated Amidation Cascade

  摘要：

  A concise synthesis of cytimidine was developed utilizing tandem Cu-mediated N-aryl amidations followed by global deprotection. This sequence exploits a regioselective coupling of an iodobenzamide with a halopyrimidine that allows the union of three fragments in a single synthetic manipulation and will permit the efficient and rapid diversification of the cytimidine core.

  peptidyl transferase center P‐site of the ribosome. The amicetin binding site overlaps significantly with that of the well‐known protein synthesis inhibitor balsticidin S. Amicetin, however, is the first compound structurally characterized to bind to the P‐site with demonstrated selectivity for the inhibition of prokaryotic translation. The natural product‐ribosome structure enabled the synthesis of simplified

  为了寻找与抗逆转录病毒疗法兼容的新型抗结核药，我们重新确定了阿米斯汀为先导化合物。结晶分析明确确定了阿米斯汀与嗜热栖热菌（Tth）的70S核糖体亚基的结合，揭示了其占据核糖体的肽基转移酶中心P-位点。Amicetin的结合位点与著名的蛋白质合成抑制剂balsticidin S显着重叠。然而，Amicetin是第一个在结构上表征与P位点结合的化合物，具有抑制原核生物翻译的选择性。天然产物核糖体结构使得能够合成简化的类似物，从而保留了抑制原核生物翻译的能力和选择性。
