An iron(III) catalyzed tandem ring opening/1,6-conjugate addition of cyclopropanols to p-quinone methides leading to γ,γ-diaryl ketones has been described. This catalytic protocol provides a novel and efficient method to access γ,γ-diaryl ketone derivatives in good to excellent yields with high functional group tolerance. Importantly, γ,γ-diaryl ketone can be further functionalized to give a versatile
已经描述了铁(III)催化的环丙醇串联开环/1,6-共轭加成到对-醌甲基化物导致γ,γ-二芳基酮。该催化方案提供了一种新颖有效的方法,可以以良好的收率获得具有高官能团耐受性的 γ,γ-二芳基酮衍生物。重要的是,γ,γ-二芳基酮可以进一步官能化以提供一组通用的有用产品。
