Abstract The reactivity of EWG (electron withdrawing group)-activated methylene group in 1,3-thiazolidin-4-one 1,1-dioxides were investigated. Novel derivatives of 1,3-thiazolidin-4-one 1,1-dioxides were prepared (the heterocyclic core was modified with carboxamide and carboxthioamide moieties as carbonyl group analogues). The products, which have functional groups for possible future modifications, are described and characterized. 相似文献

A simple and efficient method is developed. Novel 2‐amino‐4‐quinolone derivatives are synthesized. The products that have several functional groups for possible future modifications are described. 相似文献

3-Pyrimidinylcoumarins have been synthesized by interacting 2- and 4-pyrimidinylacetonitriles with substituted salicylic aldehydes,
but 9-pyrimidinylpyrano[2,3-f]chromene-4,8-diones were obtained with 8-formyl-7-hydroxychromones. Modification of the corresponding
7-hydroxycoumarins was carried out by acylation and aminomethylation. 相似文献

The reaction of 2-(2-azahetaryl)-3-oxo-4-chlorobutyronitriles with substituted benzaldehyde hydrazones gives 4-arylideneamino-2-(1-R-benzimidazol-2-yl)-3-oxobutyronitriles, the structures of which were proved using spectroscopic data, the results of elemental analysis, and through their chemical reactions. It was found that the reaction course depends on the basicity of the heterocyclic fragment in the starting nitrile. A likely mechanism for the process is proposed. 相似文献

Alkylation of 3- and 4-(5-amino-4-hetaryl-2,3-dihydro-3-oxopyrrol-1-yl)benzoic acids with phenacyl bromides or chloroacetanilides in DMF in the presence of triethylamine occurs at the carboxy group with high selectivity and yields the corresponding phenacyl and arylcarbamoylmethyl esters. The initial pyrrolylbenzoic acids were synthesized by reaction of 3- and 4-aminobenzoic acids with 4-chloro-2-hetaryl-3-oxo-butyronitriles. 相似文献
