A novel and efficient procedure for the synthesis of polysubstituted pyrroles has been developed in this work. The polysubsituted pyrroles were synthesized directly from terminal alkenes, amines and β-keto esters through cross-couplingâcyclizationâoxidation in the presence of a catalytic amount of cuprous chloride. This method provides a one-pot synthesis route from terminal alkenes to polysubstituted pyrroles for the first time and opens a new area in cuprous catalysis.
本文开发了一种新颖且高效的多取代吡咯合成方法。多取代吡咯是通过与终端烯烃、胺和β-酮酯在少量氯化亚铜催化剂存在下进行交叉耦合-环化-氧化反应直接合成的。这种方法首次提供了从终端烯烃到多取代吡咯的一锅合成路线,为亚铜催化开辟了新领域。
