Hydrogen-bonding catalysts have been found to catalyze one-pot three-component reactions of pyruvate, anilines and aldehydes to afford versatile 3-amino-1,5-dihydro-2H-pyrrol-2-ones in high yields. Both, thioureas and phosphoric acids are viable catalysts for these reactions and have comparable activity. The corresponding chiral thioureas and phosphoric acids have also been used in these three-component
已发现氢键催化剂可催化丙酮酸、苯胺和醛的一锅三组分反应,以高产率提供多功能的 3-氨基-1,5-二氢-2H-吡咯-2-酮。硫脲和磷酸都是这些反应的可行催化剂,并且具有相当的活性。相应的手性硫脲和磷酸也已用于这些三组分反应中,以高产率和中等对映选择性得到吡咯-2-酮。(© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2008 )
