Steps:
2.2.1. Synthesis of (E)-3-(4-methoxyphenyl)-1-(p-tolyl)prop-2-en-1-one(MTP), (E)-1,3-di-p-tolylprop-2-en-1-one (DTP), (E)-3-(4-(diethylamino)phenyl)-1-(p-tolyl)prop-2-en-1-one (DEP)
General procedure: Chalcones were synthesized by previously reported procedure asgiven in Fig. 2, through base catalyzed condensation of substitutedacetophenones and substituted benzaldehydes [31]. To a solution ofacetophenone (0.01 mol) in ethanol (40 ml), benzaldehyde (0.01 mol)derivative was added. Then solution of aqueous KOH (60%, 10 ml) wasadded with continuous stirring for 30 min. The mixing was continuedfor 2-3 h at room temperature. After completion of reaction whichwas confirmed by thin layer chromatography, ice cold HCl (25 ml,10%) was added. The solid was obtained which was separated by filtrationfollowed by washing with ice cold water till neutralization. Finallyproductwas recrystallizedwith ethanol. All three chalcone derivativeswere characterized by NMR, IR and Mass Spectroscopy. NMRspectra of all compounds are shown in Fig. 3 (a-c) and 13C NMR, IRand Mass Spectra of these compounds are separately given in SI file. 2.2.1.1. MTP. Mol.
