    vanadium catalyst for enantioselective oxidative coupling of phenols is reported, ultimately resulting in a simple monomeric vanadium species combined with a Brønsted or Lewis acid additive. The resultant vanadium complex is found to effect the asymmetric oxidative ortho–ortho coupling of simple phenols and 2-hydroxycarbazoles with good to excellent levels of enantioselectivity.

    The first examples of asymmetric oxidative coupling of simple phenols and 2-hydroxycarbazoles are outlined. Generation of a more vanadium catalyst by ligand design and by addition of an exogenous Brønsted or Lewis acid was found to be key to coupling the more oxidatively resistant phenols.

  • Asymmetric Total Synthesis of Chaetoglobin A

    日期:2023.6.2
    An asymmetric total synthesis of chaetoglobin A was achieved. Atroposelective oxidative coupling of a phenol incorporating all but one carbon of the final product was used as a key step to generate axial chirality. The stereochemical outcome of the catalytic oxidative phenolic with the highly substituted phenol used herein was found to be opposite that of the simpler congeners reported previously,
    实现了毛珠蛋白A的不对称全合成。包含最终产物中除一个碳以外的所有碳的苯酚的天体选择性氧化偶联被用作产生轴向手性的关键步骤。发现催化氧化酚与本文所用的高度取代的苯酚的立体化学结果与之前报道的较简单的同源物的立体化学结果相反,这提供了关于将不对称过程从简单底物外推到更复杂底物的警示故事。概述了酚后偶联步骤的优化,包括甲酰化、氧化脱芳构化和选择性脱保护步骤。由于邻近的酮基团的激活,毛球蛋白 A 的叔乙酸酯非常不稳定,这使得每个步骤都变得复杂。相比之下,最终的氧到氮的交换很容易进行,并且合成材料的光谱数据在所有方面都与分离的天然产物相匹配。
