General, mild and efficient synthesis of β-enaminones catalyzed by ceric ammonium nitrate
Sridharan, Vellaisamy,Avenda?o, Carmen,Menéndez
, p. 881 - 884 (2008/02/02)
Ceric ammonium nitrate catalyzes the reaction between aromatic or aliphatic primary amines and a variety of β-dicarbonyl compounds, including β-ketoesters, β-ketothioesters and β-diketones. The reaction proceeds smoothly at room temperature in short react
Phosphotungstic acid catalysed synthesis of β-enamino compounds under solvent-free conditions
Li, Geng-Chen
, p. 696 - 698 (2008/09/20)
A convenient eco-friendly procedure has been developed for the synthesis of β-enaminones and β-enamino esters by reacting 1,3-dicarbonyl compounds with amines in the presence of catalytic amounts of phosphotungstic acid (H3PW12O40,1 mol%). The reaction proceeds smoothly at room temperature under solvent-free conditions and gives the corresponding β-enamino compounds in high to excellent yields.
A solvent-free synthesis of β-amino-α,β-unsaturated ketones and esters catalysed by sulfated zirconia
Zhang, Zhan-Hui,Song, Li-Ming
, p. 817 - 820 (2007/10/03)
β-Amino-α,β-unsaturated ketones and esters are synthesised by the condensation of β-dicarbonyl compounds with amines in the presence of a solid superacid sulfated zirconia (SO42-/ZrO 2, SZ) under solvent-free conditions.
