Tuned Classical Thermal Aromatization Furnishing an Estrogenic Benzoacridine
摘要:
The diversity-oriented doubling strategy, which generates two 12-arylbenzoacridines from a single triarylmethanol precursor was developed to construct a library of drug candidates for the identification of biologically active compounds. Exploration of this 12-arylbenzoacridine library furnished a 4-OH derivative as an estrogenic compound.
novel palladium-catalyzed protocol for the synthesis of 9-arylacridines via tandem reaction of 2-(arylamino)benzonitrile with arylboronic acids in water has been developed with good functional group tolerance. The present synthetic route could be readily scaled up to gram quantity without difficulty. This methodology was further extended to the synthesis of a 4′-OH derivative, which showed estrogenic
Oxadisilole-fusedacridines, dioxatrisilole-fused acridines and benzo[b]acridines were synthesized through nucleophilic additions and aromatization reactions of arynes with 2-aminoaryl ketones or 2-aminoaryl aldehydes in good yields at room temperature. The photophysical, redox and thermal properties of these compounds were characterized. These compounds show potential applications as strong deep-blue

benzophenone promoted by BF3•Et2O has been developed. The reaction goes through the intramolecular Friedel–Crafts acylation and dehydration with a facile work-up procedure. It shows good functional group tolerance and the yields of acridines are mostly in range of 90–99 %. The efficiency of this reaction is tremendously high, which can be completed within 30 min.
