A general and simple procedure was 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 niobium pentachloride. The reaction proceeds smoothly at room temperature under solvent-free conditions and leads to chemo- and regioselective formation of enamine derivatives in high to excellent yields.

An efficient method for the enamination of 1,3-dicarbonyl compounds by employing ceric ammonium nitrate (CAN) as the catalyst has been described. A variety of β-amino-α,β-unsaturated ketones and esters have been synthesized in excellent yield within a short reaction time under solvent-free conditions.
A solvent-free synthesis of β-amino-α,β-unsaturated ketones and esters catalysed by sulfated zirconia

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.

Bentonite K10 clay has been used to catalyze the formation of enamino carbonyl derivatives, 2-methyl-1H-benzimidazoles, Hantzsch 1,4-dihydropyridines, Hantzsch pyridines, 2-substituted 1,3-diphenylimidazolidines, and tetrahydropyranylbenzazoles.
2-Methylpentane-2,4-Dioxysilicon(IV) Complexes of 4-(Alkyl or Aryl)Amino-3-Pentane-2-One
Singh, R. V.,Tandon, J. P.
, p. 864 - 867 (2007/10/02)
2-Methylpentane-2,4-dioxysilicon(IV) complexes of the type Si(SB)2(C6H12O2) (where SBH and C6H14O2 represent the monofunctional bidentate Schiff base and 2-methylpentane-2,4-diol molecules respectively) have been synthesized by the reactions of silicon te
