(5Z,5′Z)-3,3′-(1,4-Phenylenebis(methylene)-bis-(5-arylidene-2-thioxothiazolidin-4-one) derivatives (5a–r) have been synthesized by the condensation reaction of 3,3′-(1,4- or 1,3-phenylenebis(methylene))bis(2-thioxothiazolidin-4-ones) (3a,b) with suitably substituted aldehydes (4a–f) or 2-(1H-indol-3-yl)2-oxoacetaldehydes (8a–c) under microwave conditions. The bis(2-thioxothiazolidin-4-ones) were prepared
通过缩合反应合成了(5Z,5'Z)-3,3'-(1,4-苯撑双(亚甲基)-双-(5-亚芳基-2-硫代噻唑并恶唑烷-4-一)衍生物(5a – r) 3,3'-(1,4-或1,3-亚苯基双(亚甲基))双(2-硫代噻唑并恶唑烷-4-酮)(3a,b)与适当取代的醛(4a-f)或2-( 1 H-吲哚-3-基)2-氧乙醛(8a – c)在微波条件下,由相应的伯烷基胺(1a,b)和二-(羧甲基)-三硫羰基(2)。2-(1 H-indol-3-yl)-2-oxoacetaldehydes(8a – c)是使用HSnBu 3从相应的酰氯(7a – c)合成的。
