5-arylmethylene-3-phenyl-4-thioxo-2-thiazolidinone derivatives have been synthesized by condensation of ω-(4-formylphenoxy)acetophenone derivatives with 3-phenyl-4-thioxo-2-thiazolidinone, in good yields. The cycloaddition of the newly synthesized compounds to N-arylmaleimides, ethyl acrylate and ω-nitrostyrene has been studied. Under thermal reaction conditions [4+2] cycloaddition proceeds with complete site-
新的 5-arylmethylene-3-phenyl-4-thioxo-2-thiazolidinone 衍生物是通过 ω-(4-formylphenoxy) acetophenone 衍生物与 3-phenyl-4-thioxo-2-thiazolidinone 缩合合成的,收率很好。研究了新合成的化合物与 N-芳基马来酰亚胺、丙烯酸乙酯和 ω-硝基苯乙烯的环加成反应。在热反应条件下,[4+2] 环加成以完全的位点和区域选择性进行,以产生新的稠合噻唑并 [2,3-d] 噻唑衍生物。图形概要
