摘要:
A series of oxocyclopenta[c]chromenes were synthesized via three component reaction of 4-hydroxycumarin, dialkyl acetylenedicarboxylate, -bromo ketones, and triphenylphosphine in the presence of catalytic amount of Fe3O4 magnetic nanoparticles (MNPs) (15mol%) under solvent-free conditions at 70 degrees C. Facile, green, easy separation of product and catalyst, and high yields of products are advantages of these reactions.
