Green Synthesis, Characterization, Photophysical and Electrochemical Properties of Bis-chalcones
International Journal of Electrochemical Science, 2014 Donor-acceptor conjugated dienes (bis-chalcones) were synthesized via an ultrasonic radiation, accomplished by the reaction between 3-acetyl-2,5-dimethylthiophene/1 (2,5-dimethyl-furan-3-yl)- ethanone and terephthalaldehyde.

Synthesis and Pharmacological Evaluation of Some Phenylpyrazolo Indoquinoxaline Derivatives
E-Journal of Chemistry, 2011 Indoloquinoxalin was fused with 2,3 diphenyl quinoxaline by a methylene bridge which was then allowed for acetylation. The acetylated product was made to react with different aromatic aldehydes to give chalcones.

Study of Michael addition on chalcones and or chalcone analogues
Journal of Saudi Chemical Society, 2012 AbstractMichael addition reaction of 1,3-diphenyl-propenone 1a, e, and f with o-amino thiophenol in the presence of indium trichloride gave the benzothiazine derivatives 2a–c. Condensation of the compound 1a, e with o-phenylene diamine in triethylamine gave the benzodiazepine derivatives 3a–b.

Phthalocyanine-chalcone conjugates
Journal of Porphyrins and Phthalocyanines, 2016 A phthalocyanine-chalcone conjugate was previously reported to retain the full photodynamic activity of the phthalocyanine and a slightly lowered antivascular effect of the chalcone. Assuming that it was due to an insufficient release of the chalcone, we described here several grafting modes applied to the preparation of phthalocyanine-chalcone ...
