Synthesis and biological activity of compounds based on 4-hydroxycoumarin

Currently, the synthesis of oxygen-containing heterocyclic compounds containing a fused benzene ring system with a pyrone cycle, represented by 4-hydroxycoumarin (4-hydroxy-2H-chromen-2-one), is of great importance due to their broad spectrum of biological activity. We found it interesting to conduct reactions of 1,5-dicarbonyl compounds based on 4-hydroxycoumarin with N-nucleophiles, both from a fundamental point of view and from the perspective of the practical application of the resulting products.

Синтез и биологическая активность соединений на основе 4-гидроксикумарина

В настоящее время синтез кислородсодержащих гетероциклических соединений, содержащих конденсированную систему бензольного ядра с пироновым циклом, представителем которых является 4-гидроксикумарин (4-гидрокси-2H-хромен-2-он), является очень важным, в связи с их широким спектром биологической активности. Нам представилось интересным проведение реакций 1,5-дикарбонильных соединений на основе 4-гидроксикумарина с N-нуклеофилами, как с фундаментальной точки зрения, так и с позиции практического применения полученных продуктов.

5-(1-Aryl-3-oxo-3-phenylpropyl)-2,2-dimethyl-1,3-dioxane-4,6-diones: synthesis and reactions with N-nucleophiles

2,2-Dimethyl-1,3-dioxane-4,6-dione (Meldrum acid, isopropylidenmalonate) is widely used by synthetic chemists due to its structural features. The dual nature of the reactivity of Meldrum acid (both electrophilic and/or nucleophilic reagent) determines the synthetic value in the construction of new heterocyclic systems with practically signifi cant properties. A wide range of biological activity has been revealed in a number of compounds containing a 2,2-dimethyl-1,3-dioxane-4,6-dione fragment in their structure.
