French-Ukrainian Journal of Chemistry, 8(2), 176–182. https://doi.org/10.17721/fujcV8I2P176-1821210.17721/fujcV8I2P176-182https://ir.library.knu.ua/handle/15071834/25433Simple and efficient synthesis of 2-(1,2,4-oxadiazol-5-yl)-2,3-dihydro-4H-chromen-4-ones is elaborated. The method relies on CDI-mediated cyclocondensation of substituted 4-oxochromane-2-carboxylic acids and amidoximes. The protocol allows the preparation of 2-oxadiazolylchromanones decorated with two pharmacophores (2,3-dihydro-4H-chromen-4-one and 1,2,4-oxadiazole) that are in high demand in drug discovery.enflavanone2-heteroaryl-4-chromanones4-oxadiazolefluorine1'-carbonyldiimidazole (CDI)Стаття
