Synthesis and chemical properties of 2-acylchromones

Methods of synthesis and reactivity of 2-formyl-, 2-alkanoyl-, 2-aroyl- and 2-trifluoroacetylchromones are summarized and systematized. It is shown that these chromone derivatives react mainly with $\mathrm{N}$-, $\mathrm{C}$- and $\mathrm{P}$-nucleophiles, as well as undergo reduction and oxidation. The conditions of these reactions and the yields of the products are reported. Special attention is focused on biologically active derivatives.
