We report a Brønsted acid mediated direct α-hydroxylation of cyclic α-branched ketones via a tandem aminoxylation/N–O bond-cleavage process. Nitrosobenzene is used as the oxidant and subsequently promotes the liberation of the free alcohol. The desired products could be isolated in moderate to good yields at a maximum tested scale of 10 mmol. Derivatizations of the obtained products are presented.
我们报告了一种Brønsted酸介导的直接α-羟基化反应,通过串联氨氧化/N-O键裂解过程对环状α-支链酮进行反应。亚硝基苯被用作氧化剂,随后促进了游离自由醇的产生。在最大测试规模为10 mmol时,所得产物的收率在中等到良好之间。所得产物的衍生物化反应也被展示。
