The reaction of mercaptoacetic acid esters with pentachloro-2-nitro-1,3-butadiene (1) provides an appropriate precursor for the synthesis of special thiazolidin-4-ones. Applying different anilines as the second constituent for the requisite cyclization step, a series of (Z)-2-allylidenethiazolidin-4-ones was obtained in yields up to 81%. Some subsequent reactions have been examined too, such as the formation of perfunctionalized 1H-pyrazoles upon treatment with hydrazine. Thiazolidinones are as well known for their physiological activities as for their application in optoelectronics.
巯基乙酸酯与五氯-2-硝基-1,3-丁二烯(1)的反应提供了合成特殊噻唑烷-4-酮的适当前体。将不同的苯胺作为必需的环化步骤的第二组分,得到了一系列(Z)-2-烯丙基噻唑烷-4-酮,收率高达81%。还研究了一些后续反应,例如与肼处理后形成富功能化的1H-吡唑。噻唑烷酮以其在生理活性和光电子应用中的应用而闻名。
