aleutianamine wherein the unique [3.3.1] ring system and tertiary sulfide of this alkaloid were constructed via a novel palladium-catalyzed dearomative thiophene functionalization. Other highlights of the synthesis include a palladium-catalyzed decarboxylative pinacol-type rearrangement of an allylic carbonate to install a ketone and a late-stage oxidative amination. This concise and convergent strategy will
阿留申胺是一种最近分离的吡咯亚氨基醌天然产物,对人胰腺癌细胞显示出有效和选择性的生物活性,针对 PANC-1 的 IC 50为 25 nM,使其成为治疗开发的潜在候选者。我们报告了一种阿留申胺的合成方法,其中该生物碱独特的[3.3.1]环系统和叔硫化物是通过新型钯催化的脱芳香噻吩官能化构建的。该合成的其他亮点包括钯催化的烯丙碳酸酯脱羧频哪醇型重排以安装酮和后期氧化胺化。这种简洁而收敛的策略将能够获得阿留申胺的类似物,并进一步研究这种独特天然产物的生物活性。
