Résumé Tris-hydroxymethylaminomethane has been demonstrated to be an efficient organocatalyst in diversity-oriented synthesis of medicinally prevalent spirochromenes by one-pot, three-component reactions between isatins, malononitrile, and enolizable CH acids like dimedone, 4-hydroxycoumarin, 4-hydroxy-N-methylquinolin-2-one, or in situ generated 2-methylpyrazolon-2-one. Biodegradability and extremely low cost of the catalyst are the noteworthy features of this chromatography-free protocol.

**摘要**
三羟甲基氨基甲烷已被证明是一种高效的非金属催化剂,通过一锅三组分反应,在药物学上重要的螺色满合成中,它能够催化靛红、丙二腈与可烯醇化的CH酸(如二甲代苯二酮、4-羟基香豆素、4-羟基-N-甲基喹啉-2-酮或现场生成的2-甲基吡唑-2-酮)之间的反应。该无色谱纯化工艺的显著特点是催化剂的生物降解性和极低的成本。
