摘要
在这项工作中,开发了一种快速高效的双香豆素合成方案。芳香醛(1等)与4-羟基香豆素(2等)在催化量的质子酸离子液体三乙胺- n -磺酸四氯铝酸盐(TSAT)的存在下,在无溶剂条件下进行了一锅准三组分反应,得到了收率高、反应时间短的化合物。
A Rapid and Highly Effectual Protocol for the Synthesis of Bis-coumarins using Triethylaminium-N-sulfonic Acid Tetrachloroaluminate under Solvent-Free Conditions
In this work, a rapid and highly effectual protocol for the synthesis of bis-coumarins has been developed. The one-pot quasi three-component reaction of aromatic aldehydes (1 eq.) with 4-hydroxycoumarin (2 eq.) in the presence of catalytic amount of protic acidic ionic liquid triethylaminium-N-sulfonic acid tetrachloroaluminate (TSAT) under solvent-free conditions afforded the mentioned compounds in high yields and short reaction times.
