Acetophenone derivatives

The 2-benzoylbenzoxazole derivatives were known for their significant biological activities such as antiproliferative activity, inhibition of FAAH enzyme (fatty acid amide hydrolase). In this study, we report a simple and efficient method for the synthesis of such compounds by the direct reaction of o-aminophenol with acetophenone catalyzed by sulfur in DMSO.

Calix[4]pyrrole derivatives with bulky substituents at their meso-positions were synthesized via mixed condensation of pyrrole with cyclohexanone and acetophenone derivatives. Anion binding studies, carried out by isothermal titration calorimetry in 1,2-dichloroethane with Cl− and CH3CO−2 anions in the form of their tetrabutylammonium salts, revealed that these new calix[4]pyrrole derivatives can bind the aforementioned anions as effectively as the unsubstituted “parent” system, octamethylcalix[4]pyrrole (1).

In this study, new polythiophenes containing hydrazone groups from derivatives of acetophenone were synthesized by chemical oxidative coupling polymerization. Ultraviolet-visible spectroscopy (UV-Vis) combined with infrared (IR) analyses proved the supposed structure of novel polythiophenes and proved conformance of the expected synthetic method. Morphology and surface properties of the synthesized polymers were investigated by field-emission scanning electron microscopy (FE-SEM).
