摘要

报道了一种简单高效的制备苯并[f]吡喃[3,2-c]铬衍生物的方法。以1-羟基- 3h -苯并[f]铬-3-酮、丙二腈和1-苄基喹啉-2,3-二酮为原料，在回流条件下超声辐照下，在乙醇中三组分反应制得7个编码为1a-7a的化合物。同样，由4-羟基香豆素、丙二腈和芳香醛三组分反应制得10个吡喃[3,2-c]铬衍生物化合物（1b-10b）。首次制备了离子液体B2，并将其用作催化剂。产品的非色谱分离纯化和高产率是该方案的显著特点。

A straightforward and high-productivity procedure for preparing benzo[f]pyrano[3,2-c]chromene derivatives is reported. 7 compounds coded as 1a-7a were prepared by a three-component reaction between 1-hydroxy-3H-benzo[f]chromen-3-one, malononitrile, and 1-benzylindoline-2,3-dione in ethanol under reflux condition and ultrasonic irradiation. Similarly, 10 compounds (1b-10b) of pyrano[3,2-c]chromene derivatives were prepared from the three-component reaction between 4-hydroxycoumarin, malononitrile, and aromatic aldehydes. Ionic liquid B₂ was prepared for the first time and used as a catalyst. The nonchromatographic separation and purification of the products with high-yield productivity are the salient features of this protocol.
