transannulation strategy using readily available tryptamines. Molecular oxygen and water are used as oxygen sources and provide direct access to the donaxaridine scaffold and its derivatives. This methodology is applied to the efficient synthesis of the natural products donaxaridine, chimonamidine, donaxanine, donaxarine, and aline in just one or two steps. The tryptamines, albeit with oxy-sensitive dialkyl N-H
我们报告了使用现成的色胺的一般铜/碘共催化含氧转环策略。分子氧和水用作氧源,并提供直接进入多那沙定支架及其衍生物的途径。该方法适用于仅通过一两个步骤即可有效合成天然产物多纳沙啶、chimonamidine、donaxanine、donaxarine 和 aline。色胺虽然具有氧敏感的二烷基N -H 基团,但通过单电子转移双氧化过程被选择性氧化。
