This method constitutes a novel approach to the challenging 1,6-dioxygenation motif. A range of γ-substituted enones, including many bearing all-carbon quaternary centers, are available through a simple protocol under mild reaction conditions with superb functional group compatibility. Excellent stereoinduction is observed providing controlled access to challenging stereochemical arrays.
使用 α-卤代羰基化合物和二烯醇醚通过 Cu(II) 催化形成一般的区域选择性和立体选择性 γ-CC 键。这种方法构成了一种具有挑战性的 1,6-双加氧基序的新方法。一系列 γ 取代的烯酮,包括许多带有全碳四元中心的,可在温和的反应条件下通过简单的方案获得,并具有极好的官能团兼容性。观察到出色的立体诱导,提供对具有挑战性的立体化学阵列的受控访问。
