Versatile syntheses of 5-imino or 5-acylidene substituted 1,3-thiazolidin-4-one derivatives are reported from α-dioxothiazole systems and phosphoranes via Wittig reactions. Antimicrobial and antioxidant activity of the compounds were evaluated. 5-Carbonylmethylene substituted 2-thioxo-1,3-thiazolidines have better antioxidant properties than the 5-arylimino substituted ones. The % inhibition value
通过Wittig反应,从α-二氧噻唑系统和膦烷中报道了5-亚氨基或5-亚亚甲基取代的1,3-噻唑烷-4-酮衍生物的多功能合成。评价了化合物的抗微生物和抗氧化活性。5-羰基亚甲基取代的2-thioxo-1,3-thiazolidines具有比5-arilimino取代的抗氧化剂更好的抗氧化性能。在相同浓度下,化合物3的%抑制值(90.8%)接近于标准BHT(93.6%)。在1,3-噻唑烷环的C-5位具有亚烷基-酰胺基的化合物5和15在合成的化合物中显示出最高的抗菌活性。
