摘要
A highly efficient synthesis of substituted conjugated dienals was developed through a triazolegold (TA-Au)-catalyzed propargyl vinyl ether rearrangement followed by an amine catalyzed allenealdehyde 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.
