2 68 83 Synthesis, configurational analysis and antimicrobial activity of imidazolidinone, thiazolidinone and isoxazolone derivatives of 9,10-phenanthrenequinone A facile synthesis of imidazolidinone, thiazolidinone and isoxazolone derivatives has been described by Knoevenagel type condensation reactions of 9,10-phenanthrenequinone with active methylene heterocycles/compounds. The products have been characterized by spectral data. Semiempirical studies have been performed to understand the stereochemical course of the reaction. Some of the synthesized products have been screened for antimicrobial activity.
