名称:
Chitosan synergistically enhanced by successive Fe3O4 and silver nanoparticles as a novel green catalyst in one-pot, three-component synthesis of tetrahydrobenzo[α]xanthene-11-ones
Niobium pentachloride catalyzed one-pot multicomponent condensation reaction of β-naphthol, aryl aldehydes
and cyclic 1,3-dicarbonyl compounds. Thus, a variety of 8,9,10,12-tetrahydrobenzo[a] xanthen-11-one derivatives were
produced in good to excellent yields.
