One-pot synthesis of three enaminones, (E)-1-(4-chlorophenyl)-3-morpholinoprop-2-en-1-one 1, (E)-1-(4-chlorophenyl)-3-(4-methylpiperazin-1-yl)prop-2-en-1-one 2, and (E)-1-(4-chlorophenyl)-3-(pyrrolidin-1-yl)prop-2-en-1-one 3 were achieved. The synthetic protocol via three components reaction of p-chloroacetophenone with DMFDMA (N,N-dimethylformamid-dimethylacetal) and the corresponding secondary amines (morpholine/N-methylpiperazine/pyrrolidine) in dioxane under heating for 2.5–4 h at 102 °C yielded the requisite enaminones. This protocol has the advantage of no separation of intermediate, no need for column purification with quantitative yield for the target compounds. The chemical features of the β-enaminones 1–3 were assigned by NMR. β-Enaminones 1, and 2 were assigned by single crystal X-ray diffraction technique. The intermolecular interactions in the crystal structures were analyzed quantitatively using Hirshfeld analysis. The Cl…H and O…H hydrogen bonds are common in both compounds while the C-H…π and N…H contacts are more significant in 2 than 1. DFT studies were investigated to show the electronic and spectroscopic properties (NMR and UV-Vis) of the studied systems.

Five new compounds have been synthesized and characterized by elemental analysis, IR, NMR and single-crystal X-ray diffraction. They present interesting assemblies in the solid state dominated by H-bonding and anion–π interactions.
