Friedel-Crafts (FC) acylation reactions were exploited in the preparation of ketone-functionalized aromatics. Environmentally more friendly, solvent-free mechanochemical reaction conditions of this industrially important reaction were developed. Reaction parameters such as FC catalyst, time, ratio of reagents and milling support were studied to establish the optimal reaction conditions. The scope of the reaction was explored by employment of different aromatic hydrocarbons in conjunction with anhydrides and acylation reagents. It was shown that certain FC-reactive aromatics could be effectively functionalized by FC acylations carried out under ball-milling conditions without the presence of a solvent. The reaction mechanism was studied by in situ Raman and ex situ IR spectroscopy.

The chemistry of phthalazine derivatives has been of increasing interest since many of these compounds have found many chemotherapeutic applications. So this study aims to synthesize a library of phthalazine derivatives and to investigate their anti-inflammatory and anti-proliferative activities. Sixteen new phthalazinone derivatives (2a-p) were synthesized and tested for their in vitro antiproliferative and in vivo anti-inflammatory activities. All the synthesized compounds were identified and characterized by IR, 1H NMR, 13C NMR spectroscopy, and MS. Two compounds, 2b and 2i, showed significant anti-inflammatory activity comparable with that of the standard drug etoricoxib in the carrageenan-induced rat paw edema model at 3 and 5 h, respectively. Three compounds (2h, 2j, and 2g) showed moderate sensitivity toward the renal cancer cell line UO-31. A library of new phthalazone compounds (2a-p) was synthesized as dual inhibitors (COX-2/LOX-5) and evaluated for their anti-inflammatory, anticancer activities. Two compounds showed significant anti-inflammatory activity comparable with that of the standard drug etoricoxib, whereas three compounds showed moderate sensitivity toward the renal cancer cell line UO-31.
