Chromone and coumarin derivatives exhibit a wide spectrum of biological activity, including spasmolytic, antiarrhythmic, cardiothonic, antiviral, and anticancer properties. Phosphorus-containing chromone and coumarin derivatives form a novel group of compounds, possessing remarkable cytotoxicity and alkylating and anticancer activity against selected tumor cell lines. Derivatives containing a phosphorus atom at position 2 of a γ-pyrone ring are known to be efficient antibacterial agents. This review presents methods developed for the synthesis of derivatives of chromone and coumarin that contain a phosphonate moiety. Among them, the reaction of derivatives of 2-hydroxyacetophenone with phosphonic compounds is the one most frequently used. Some analogues were characterized by X-ray crystallography. 相似文献

Abstract Some new sulphonyl-N-heterocyclo-8-hydroxy quinolines have been synthesised by the reaction of 8-hydroxyquinoline-5-sulphonyl hydrazide with different active methylene compounds. The pyrazole, pyrazoline, pyrazolidine and pyridazine derivatives were reacted with some metal cations to give the corresponding chelates. All synthesized compounds have been screened in vitro for their biological activities. 相似文献

ABSTRACT N-Phenyliminophosphorane (1) reacts with 9,10-phenanthrenequinone (2a) to give the new products 2-phenylphenanthro[9,10-d][1,3,2]dioxazole (4a) and (10Z)-10-(phenylimino)-9(10H) phenanthrenone (4b). The reaction of 1 with 1,2-naphthoquinone (2b) afforded both the dioxazole derivative 5a and the known 2-anilino-naphthoquinone-1,4-anil (5b). On the other hand, 2,6-di-tert-butyl-2,3-diphenyl-2,3-dihydro-1,2,3-benzoxadiazole (6) was obtained from the reaction of (2c) with phosphinimine (1). Application of reagent 1 on 2d and 2e renders (6E)-2,3,4,5-tetrahalogeno-6-(phenylimino)-2,4-cyclohexadien-1-one 7a and 7b, respectively. Moreover, p-quinones (3a–3c) react with phosphinimine (1) to yield products 8, 9 and 10, respectively. Mechanisms accounting for the formation of the new products are discussed and the probable structures of the products are presented based on analytical and spectroscopic data. 相似文献

Condensation of thiazolinone 1 with benzaldehydes 2a, b in ethanolic piperidine afforded the methylidene derivatives 3a, b. Cyclocondensation of compound 3b with malononitrile furnished the novel thiazolo[3,2-a]-pyridine 5. Also, compound 3b was condensed with dimethylformamide-dimethylacetal (DMF-DMA) and triethylortho-formate to yield N,N-dimethylamino 6 and ethoxymethylene 7 derivatives respectively. The novel thiazolo[3,2-a]pyridines 10a, b were obtained by cyclocondensation of compounds 3a, b with benzylidene-malononitriles 8a, b. Similarly, cyclocondensation of compound 3b with benzylidenemalononitrile 11 afforded the thiazolopyridines 12a–c. Ternary condensation of compound (12), 4-morpholinobenzaldehyde 2b and malononitrile (1:1:1 molar ratio) produced the thiazolopyridines 14a–c. When compound 10b was subjected to react with malononitrile in dioxane/piperidine under reflux the novel condensed heterocyclic system 18 was obtained. Treatment of ortho-aminocarbonitrile 10b with formic acid, aromatic aldehyde and triethylorthoformate furnished the thiazolo[2′,3′:1,6] pyrido[2,3-d] pyrimidine 20, azomethine 21a, b and ethoxymethylene 22 derivatives respectively. The structure of the synthesized compounds was established by analytical and spectral data. 相似文献
