derivatives, are chemically inert due to their intrinsic aromaticity and low polarity. The catalytic asymmetric dearomatization (CADA, coined by You and co-workers) of the nonactivated arenes represents a formidable challenge. We herein demonstrated an organocatalytic asymmetric dearomatizing hetero-Diels–Alderreaction of benzene derivatives. The tunable regioselectivity of this strategy allowed delivery of
非活化芳烃,如苯衍生物,由于其固有的芳香性和低极性,在化学上是惰性的。非活化芳烃的催化不对称脱芳构化(CADA,由 You 及其同事创造)是一项艰巨的挑战。我们在此证明了苯衍生物的有机催化不对称脱芳构化杂-Diels-Alder 反应。该策略的可调区域选择性允许以优异的立体选择性递送多种立体化学复杂的多环化合物和氧杂环己烷。产品的高度复杂性和三维度对其在材料科学和药物发现中的潜在应用至关重要。机理研究表明,该反应通过手性四取代亚乙烯基进行邻苯醌甲基化物 (VQM) 中间体,它非常有效地克服苯衍生物的芳香性损失以及伴随的手性转移。
