A convenient method for the synthesis of 1,3-dienes from readily available compounds is reported. 2-Aryoxy-1,3-dienes are produced stereoselectively by a nickel-catalyzed reaction of propargyl carbonates with phenols. Functional group tolerance is broad to allow iodo, formyl, and boryl groups. The resulting 1,3-dienes are of much synthetic value because they can participate in a wide variety of reactions
报道了一种从容易获得的化合物合成 1,3-二烯的简便方法。2-芳氧基-1,3-二烯通过镍催化的碳酸炔丙酯与苯酚的反应立体选择性地产生。官能团耐受性很广,以允许碘、甲酰基和硼酰基。所得的 1,3-二烯具有很高的合成价值,因为它们可以参与多种反应,包括 Diels-Alder 反应。
