A novel reactivity of dimethyldioxirane, generated in situ from Oxone and acetone, with substituted phenols and naphthols is reported. This methodology allowed the synthesis of ortho‐quinols or epoxy ortho‐quinols from a site‐selective oxidative dearomatization process, with good yields under very mild conditions. A short total synthesis of natural product lacinilene C methyl ether is also described
报道了由Oxone和丙酮原位生成的二甲基二环氧乙烷与取代的酚和萘的新型反应性。该方法允许合成邻-quinols或环氧邻-quinols从站点选择性氧化脱芳构化过程中,随着非常温和的条件下具有良好的产率。还描述了使用该方法作为关键步骤的天然产物紫杉烯C甲醚的短暂全合成。
