The review summarizes and systematizes the literature data on the methods of synthesis and chemical properties of 2-ylidene-1,3-thiazolidines and 2-ylidene-2,3-dihydro-1,3-thiazoles. Two general approaches to their preparation have been identified: the construction of the 2-ylidene-1,3-thiazolidine ring from acyclic precursors in one synthetic process and the introduction of the 2-ylidene fragment into the 1,3-thiazolidine ring. The main chemical transformations of 2-ylidene-1,3-thiazolidines and 2-ylidene-2,3-dihydro-1,3-thiazoles, which include the reactions of selective functionalization and heterocyclization at the ylidene fragment and thiazolidine backbone, are considered. The bibliography of the review consists of 97 references published from 2000 to 2020.

综述总结并系统化了有关2-亚基-1,3-噻唑烷和2-亚基-2,3-二氢-1,3-噻唑的合成方法和化学性质的文献数据。已经确定了两种通用的制备方法：在一种合成方法中由无环前体构建2-亚丙基-1,3-噻唑烷环，以及将2-亚甲基片段引入1,3-噻唑烷环。考虑到了2-亚基-1,3-噻唑烷和2-亚基-2,3-二氢-1,3-噻唑的主要化学转化，包括在亚烷基片段和噻唑烷骨架上的选择性官能化和杂环化反应。该评价的书目包含2000年至2020年出版的97篇参考文献。
