A method for asymmetric α-arylation of amino acid derivatives has been developed. The arylation was performed by Clayden rearrangement of ester enolates via memory of chirality to give hydantoins with an aryl-substituted tetrasubstituted carbon with up to 99% ee.
已经开发了一种氨基酸衍生物不对称α-芳基化的方法。芳基化是通过酯烯醇的克莱登重排通过手性记忆进行的,得到具有高达 99% ee 的芳基取代的四取代碳的乙内酰脲。
