An efficient and one-pot synthesis of multisubstituted pyrroles with high diversity and in a regioselective manner from the reactions of suitably substituted (Z)-enynols with amines or sulfonamides under mild reaction conditions has been developed. This synthesis was realized via a cascade process in the presence of gold/silver (Au/Ag) or boron trifluoride⋅etherate/gold/silver (BF3⋅Et2O/Au/Ag) catalysts
已经开发了由适当取代的(Z)-烯醇与胺或磺酰胺在温和的反应条件下的反应以区域选择性的方式高效且一锅合成高多样性的多取代吡咯的方法。该合成实现了通过在金/银(金/银)的存在下,级联过程或硼trifluoride⋅etherate/金/银(BF 3 ⋅Et 2 O /金/银)催化剂,它可以催化胺化和环异构反应在同一艘船上。
