Kostanecki reaction

Also known as Kostanecki-Robinson reaction. Transformation 1— 2 represents an Allan-Robinson reaction (see page 3), whereas 1 3 is a Kostanecki (acylation) reaction

Although the literature refers to the formation of chromones/coumarins as the Kostanecki reaction (and often the Kostanecki-Robinson reaction) and the synthesis of flavones as the Allan-Robinson reaction, others have chosen to merge the two reactions and refer to both transformations as the Kostanecki-Robinson reaction. This section will follow the latter school of thought, and use the Kostanecki-Robinson (K-R) nomenclature.
