Synthesis and Crystal Structure of 1-Carboxymethy-6-(p-Methy-Phenyl)-1,2,3,4,5,6-Hexahydroindeno[2,3-b]Quinoline-5,11-Dione under Microwave Irradiation

The title compound(C27H25NO4) has been synthesized by the reaction of p-methyl-benzaldehyde,1,3-indanedione and 5,5-dimethyl-3-(carboxymethylamino)cyclohex-2-enone in acetic acid under microwave irradiation.The structure was determined by single crystal X-ray diffraction.The crystal is triclinic,space group P1 with a=0.990 0(3) nm,b=1.096 7(3) nm,c=1.308 1(3) nm,V=1.233 7(5) nm3,Z=2,Dc=1.275 g/cm3,μ=0.087 mm-1,F(000)=504.The structure was solve by direct methods and refined by full-matrix least squares method to the final R=0.098 4,ωR=0.168 5.X-ray analysis reveals that the dihedral angle between the benzol and pyridine planes is 88.94°.
