Abstract
AbstractButyrate derivatives of allyl 2-acetyl-3-(phenylamino)butanoate (1) and 1,3-dioxane derivatives of 2,6-dimethyl N-(4-methylphenyl)-1,3-dioxan-4-amine (2) and N-(3,5-diflourophenyl)-2,6-dimethyl-1,3-dioxan-4-amine (3) were synthesised. Their structures were characterized by FTIR (1) 1H NMR, 13C NMR spectroscopic techniques and single crystal X-ray diffraction. The compound (1) crystallizes in the triclinic crystal system with the space group p-1 with a = 10.0874(5) Å, b = 10.1751(5) Å, c = 14.1930(8) Å, α = 82.429(4)°, β = 77.482(4)°, γ = 80.820(4)°, v = 1396.77(13) Å3. The compound (2) crystallizes in the monoclinic space group P21/C with unit cell dimensions a = 9.8454(3) Å, b = 13.3032(4) Å, c = 10.1967(3) Å, α = 90°, β = 114.821(2)°, γ = 90°, v = 1212.15(6) Å3. The compound (3) crystallizes in the triclinic space group p-1 with unit cell dimensions a = 9.65630(10) Å, b = 11.2266(2) Å, c = 11.2658(2) Å, α = 83.7710(10)°, β = 79.1770(10)°, γ = 77.1290(10)°, v = 1166.59(3) Å3. Graphical AbstractIn the crystal packing of all the three crystal structures, the molecules are linked together by hydrogen bonds to form dimers.
