cross-coupling of propargylic mesylates and Grignard reagents for the synthesis of diverse chiral allenes catalyzed by a recyclable heterogeneous nanocopper catalyst is reported. The synthetic utility of this sustainable methodology was further demonstrated by its application to the asymmetric total synthesis of 5 valuable allenic natural products.
据报道,甲磺酸丙炔酯和格氏试剂高效、立体定向交叉偶联,用于由可回收的非均相纳米铜催化剂催化合成多种手性丙二烯。通过将其应用于 5 种有价值的丙二烯天然产物的不对称全合成,进一步证明了这种可持续方法的合成效用。
