A rapid method for the synthesis of meta-substituted alkoxybenzenes is achieved by oxidation of cyclohexenones. This one-pot transformation is catalyzed by molecular iodine with DDQ as an oxidant in the presence of alcohols. Diverse cyclohexenones with aryl or alkyl substitutes are well tolerated to the mild oxidative conditions affording desired products in up to 92% yield. These oxidizing processes
一种合成间位取代烷氧基苯的快速方法是通过氧化环己烯酮来实现的。这种一锅法转化是由分子碘催化的,DDQ 作为氧化剂,在醇的存在下。具有芳基或烷基取代基的各种环己烯酮对温和的氧化条件具有良好的耐受性,可提供高达 92% 产率的所需产物。这些氧化过程适用于有效合成有用的间位取代酚类产品,这些产品很难通过传统的亲电取代获得。
