A highly efficient synthesis of substituted conjugated dienals was developed through a triazole–gold (TA–Au)-catalyzed propargyl vinyl ether rearrangement followed by an amine catalyzed allene–aldehyde tautomerization. Various substituted vinylogous aldehydes were prepared in one pot with good to excellent yields (up to 95%) under mild conditions with high atom economy.
通过三唑-金(TA-Au)催化的炔丙基乙烯基醚重排,然后由胺催化的丙二烯-醛互变异构,开发了一种高效的取代共轭二烯合成方法。在温和的条件下以高原子经济性,在一个锅中制备各种取代的乙烯基醛,收率好至极好(高达95%)。
