An eco-friendly procedure for the synthesis of polysubstituted quinolines under aqueous media
摘要:
Some new metal dodecyl sulfates were prepared by the reaction of sodium dodecyl sulfate and the corresponding metal nitrates. All of the prepared salts catalyzed the synthesis of quinoline from o-aminoaryl ketones and ketones or beta-diketones. Among the metal dodecyl sulfates, zirconium tetrakisdodecyl sulfate, was superior to others. Polysubstituted quinolines were synthesized from the same starting materials in the presence of a catalytic amount of Zr(DS)(4) in good to high yields in water under reflux conditions. Zr(DS)(4) could be recovered and reused. (c) 2006 Elsevier B.V. All rights reserved.
facile hydrothermal treatment of cupric dodecylsulfate (Cu(DS)sub2}) and NaOH aqueoussolution at 120 deg. C. The products were characterized by powder X-ray diffraction, transmission electron microscopy, scanning electron microscopy, selected area electron diffraction, X-ray photoelectron spectroscopy and UV-vis absorptionspectroscopy, respectively. A possible mechanism was also proposed to account
