    • A method of synthesizing a compound having a 1,3-thiazolidin-4-one ring appended at the 2-position by a double bond to the active methylene position of a ketomethylene or malononitrile moiety, the method comprising reacting the corresponding ketomethylene compound or malononitrile with an isothiocyanate in the presence of a base, reacting the resulting product with a haloacetic acid or haloacetic ester, followed by eliminating water or alcohol to form the 1,3-thiazolidin-4-one ring. A method of forming a dye, using as a starting material a compound having a 1,3-thiazolidin-4-one ring appended at the 2-position by a double bond to the active methylene position of a ketomethylene or malononitrile moiety. The method including appending a fragment necessary to complete a merocyanine, oxonol, hemicyanine, benzylidene, cinnamylidene or holopolar cyanine dye, to the 5-position of the 1,3-thiazolidin-4-one ring.
    • 一种通过双键将2-位上的1,3-噻唑烷-4-酮环与酮亚甲基或丙二腈部分的活性亚甲基合成的方法,该方法包括使相应的酮亚甲基化合物或丙二腈 与异硫氰酸酯在碱存在下反应,将所得产物与卤代乙酸或卤代乙酸酯反应,然后除去水或醇形成1,3-噻唑烷-4-酮环。 一种形成染料的方法,用作为起始原料的具有1,3-位噻唑烷-4-酮环的化合物,该化合物在2-位通过双键连接到酮亚甲基或丙二腈部分的活性亚甲基位置。 该方法包括将完成部花青,氧杂醇,半花青,亚苄基,肉桂亚基或环戊烯花青染料所必需的片段添加到1,3-噻唑烷-4-酮环的5-位。
