In this study, a series of 4-aryl-6,6-dimethyl-1,2,3,4,5,6,7,8- octahydroquinazoline-2,5-diones were synthesized by condensing urea with 4,4-dimethyl-1,3-cyclohexanedione and appropriate aromatic aldehydes according to the Biginelli reaction. The structures of the compounds were characterized by spectroscopic methods. The racemic compounds were resolved into
Thermochemical and theoretical studies on cyclohexanediones.
