The title compound has been synthesized via a green microwave-assisted one-pot reaction of isophthalaldehyde with 3-(p-tolylamino)-5,5-dimethylcyclohex-2-enone and tetronic acid in glacial acetic acid (HOAc) and N,N-dimethylformamide (DMF), and its structure was determined by monocrystalline X-ray diffraction. The crystal is triclinic, space group P-1 with a 1.162 15(14), b=1.339 02(16), c=1.478 23(19) nm,α=96.226(2)°, β=94.729(2)°γ= 106. 956(3)°, Mr=720. 83, V=2. 171 6(5) nm^3, Dc=1. 102 g/cm^3, Z=2, μ (Mo Ka)=0. 073 mm^-1 ,F(000)=764. The structure was solved by direct methods and refined by the full-matrix method of least-squares to the final R=0. 098 1, R=0. 126 3.
