报道了稀土化合物Yb(OTf)3催化的苯乙酮、芳香醛和芳香胺Mannich反应, 三组分“一锅法”合成了一系列的β-氨基酮衍生物. 该方法操作简单、条件温和、产率较高、催化剂可重复使用, 且对环境友好.

关键词: Yb(OTf)3, Mannich反应, 芳香醛, β-氨基酮衍生物, 芳香胺

The three component “one-pot” Mannich reaction of acetophenone with aromatic aldehydes and aromatic amines catalyzed by Yb(OTf)3 afforded the corresponding β-amino ketone derivatives in high yields under mild conditions. The catalyst Yb(OTf)3 was recycled easily and thus regarded as environmentally-friendly catalyst.

Key words: Mannich reaction, Yb(OTf)3, aromatic aldehyde, β-amino ketone derivative, aromatic amine
