We report the intermolecular palladium-catalyzed reaction of tert-butyl propargyl carbonate with tryptamine derivatives or other indole-containing bis-nucleophiles. The reaction proceeds under mild conditions and with low catalyst loadings to afford novel spiroindolenine products in good to high yields.
我们报告了叔丁基炔丙基碳酸酯与色胺衍生物或其他含吲哚的双亲核试剂的分子间钯催化反应。该反应在温和条件下和低催化剂负载下进行,以良好至高产率提供新型螺吲哚产品。
