A microwave-assisted, rapid and efficient method using boron trifluoride etherate (BF3.Et2O) for the synthesis of acridones, via an intramolecular acylation of N-phenylanthranilic acid derivatives, has been developed. The reaction proceeds under solvent-free conditions, tolerates a wide range of functional groups, and provides rapid access to a range of acridones in good to excellent yields. Several of the synthesized acridones exhibited potent antimalarial activities against CQ sensitive and multi-drug resistant (MDR) parasites.

Paragraph 0049-0051, (2021/02/06)
The invention relates to an acridine compound and an application thereof. The structural formula of the acridine compound is shown as a formula (I), wherein Ar is selected from substituted or unsubstituted aryl or substituted or unsubstituted heteroaryl, R1 and R2 are respectively and independently selected from H, substituted or unsubstituted alkyl, substituted or unsubstituted aryl or substituted or unsubstituted heteroaryl, R1 and R2 are respectively and independently selected from H, substituted or unsubstituted alkyl, substituted or unsubstituted aryl or substituted or unsubstituted heteroaryl, and x is selected from oxygen or sulfur. The acridine compound provided by the invention has good electron transport performance and hole transport performance, so that the acridine compound can be used as a material of a hole transport layer and an electron transport layer, due to the fact that the acridine compound has a high triplet state energy level, the acridine compound becomes a good bipolar main body material, the acridine compound is used as the main body material of a light-emitting layer, more exciton energy can be transmitted to a light-emitting body, and the light-emittingefficiency of a light-emitting device is improved.

By starting from a common substrate, 2-aminobenzaldehyde, both acridines and acridones were prepared. The former were generated in high yields by copper-catalyzed N-arylation followed by acid-mediated cyclization while the latter were obtained by double copper-catalyzed N-arylation followed by cyclization under the same reaction conditions. Moreover, acridine was subjected to deprotometalation by recourse to a lithium-zinc base and converted to the corresponding 4-iodo derivative, which was involved in copper-catalyzed couplings with pyrrolidinone and pyrazole. Finally, addition of pyrazole, indole and carbazole onto the 9 position of bare acridine was improved. While moderate biological activity was noticed in melanoma cells growth inhibition, the newly prepared compounds feature interesting photophysical properties which were evaluated in a preliminary study.
