A water mediated multicomponent reaction for the synthesis of novel spirooxindole derivatives and their antifungal activity
ORGANIC & BIOMOLECULAR CHEMISTRY(2024)
摘要
A water mediated three-component reaction of isatin, 4-aminocoumarin, and 1,3-cyclodicarbonyl compounds is reported for the synthesis of spiro[chromeno[4,3-b]cyclopenta[e]pyridine-7,3 '-indoline]trione and the spiro[chromeno[4,3-b]quinoline 7,3 '-indoline]trione. Up to 27 different spirooxindole derivatives were synthesized by this method. The bioactivity of these spirooxindole derivatives was evaluated and they were found to show antifungal activity against Cercospora arachidicola, Physalospora piricola, Rhizoctonia cerealis, and Fusarium moniliforme. A total of 27 novel spirooxindoles were synthesized through a water mediated three-component reaction of isatin, 4-aminocoumarin, and 1,3-cyclodicarbonyl compounds. Several compounds showed excellent antifungal activity against Physalospora piricola.
