    Résumé Organocatalyst trityl chloride (Ph3CCl), by in situ formation of trityl carbocation with inherent instability, efficiently promotes the cross-aldol condensation reaction between cycloalkanones and arylaldehydes in solvent-free and homogeneous media to afford α,α′-bis(arylidene)cycloalkanones in high yields. Moreover, an attractive and plausible mechanism based on observations and the literature is proposed for the reaction.

    decrease in total energy (ranging from −75.50 to −100.84) for all the synthesized compounds which were less than levamisole (−50.69) revealing higher binding with the enzyme. The compounds were synthesized by Clasien–Schimdt condensation and their effect was observed on the activity of acid and alkaline phosphatases. The results showed that synthesized bischalcones were inhibitory to alkaline phosphatases
