Abstract:: Medicinal chemists have continuously shown interest in new curcuminoid derivatives, the diarylpentadienones, owing to their enhanced stability feature and easy preparation using a one-pot synthesis. Thus far, methods such as Claisen-Schmidt condensation and Julia-Kocienski olefination have been utilised for the synthesis of these compounds. Diarylpentadienones possess a high potential as a chemical source for designing and developing new and effective drugs for the treatment of diseases, including inflammation, cancer, and malaria. In brief, this review article focuses on the broad pharmacological applications and the summary of the structure-activity relationship of molecules which can be employed to further explore the structure of diarylpentadienone. The current methodological developments towards the synthesis of diarylpentadienones are also discussed.

First Time

The rate-accelerating effects of fluoroalcohol solvents for generating trivalent hypervalent iodine species and the conversion into diaryliodonium(iii) salts have been used for the first time to realize a facile and clean one-pot synthesis of diaryliodonium(iii) salts 3 from aryl iodides 1 and suitable arene partners 2 with peracetic acid (PAA). The use of PAA as a green and practical oxidant is significantly effective in fluoroalcohol solvents. The scope and limitations of the methodology are elucidated by investigation of a wide variety of representative substrates.
