For the first time, the literature data on the methods of synthesis and reactivity of 3-(1--alkynyl)chromones are summarized and systematized. The main method of obtaining these compounds is the Sonogashira cross-coupling reaction of 3-halogenchromones with terminal acetylenes, and the most important chemical properties are transformation into furans, reactions with dinucleophiles, ambiphilic [4+2]- and [4+3]-cyclizations, as well as dimerization processes and mixed condensation of 2-methyl-3-(1-alkynyl)chromones due to the vinylogous methyl group. With the exception of oxacyclization to furans, chemical transformations of 3-(1-alkynyl)chromones are accompanied by recyclization of the pyrone ring, in which not only the carbonyl group, but also the triple bond can take part. This significantly increases the synthetic significance of these compounds and ensures the production of more complex heterocyclic systems on their basis. The mechanisms of the reactions are discussed, the conditions for their implementation and the yields of the resulting products are indicated.
