Numerous new spiroindenoquinoxalines containing pyrano groups were synthesized via a one-pot, three-component reaction of indenoquinoxaline, malononitrile with various α-methylenecarbonyl compounds (β-diketones, pyrazolones) catalyzed by triethylamine.
通过在
吲哚喹喔啉、
丙二腈与各种α-亚甲基羰基化合物(
β-二酮、
吡唑酮)之间进行一锅法三组分反应,在
三乙胺的催化下,合成了许多含有
吡喃基团的新型螺
吲哚喹喔啉。
