5-[2-(4-氯苯基)乙烯基]-3-甲基-4-硝基-1,2-恶唑 | 3-methyl-4-nitro-5-(4-chlorostyryl)isoxazole | 53557-97-4 | C12H9ClN2O3 | 264.668 |
A simple, efficient, economical and environmentally benign method has been developed for one-pot three component synthesis of isoxazolyl amino chromeno[4,3-b]pyridine derivatives from 4-amino-3-methyl-5-styrylisoxazoles, malononitrile and (E)-3-benzylidenechroman-4-one by using acetic acid (AcOH) as a promoter and water as a green reaction medium under thermal condition. The interesting features of this method are environmental friendly, metal-free, less reaction time, wide substrate scope, operational simplicity, easy purification of products and good yields.
