Visible-light irradiation of chalcones: expanding the scope of photocatalysis

Abstract

Chalcones, an important class of α,β-unsaturated compounds, have garnered significant attention because of their pharmacological and biological importance. Due to their exceptional redox properties and triplet energy state, visible-light irradiation of chalcones can profoundly impact their reactivity, opening novel avenues for synthetic applications. In this review, a comprehensive overview of visible-light irradiation of chalcones has been presented, along with the underlying mechanisms involved and the resulting transformations. By elucidating the complex interplay between visible light and chalcone reactivity, this review seeks to inspire researchers working in the field of medicinal chemistry, asymmetric catalysis, and photochemical and sustainable organic synthesis.
