Abstract

Thiazolidines (TZs) are a significant class of heterocyclic compounds displaying several pharmaceutical, and biological activities. Because of our interest in the chemistry and biology of heterocycles, with the exploitation of ionic liquids (ILs) in organic transformations, herein, the recent preparative developments for TZs in ILs are deliberated wherein ILs play the dual role of solvent and catalysts. The preparation of various types of TZs, namely 1,3-thiazolidine-4-ones bearing azo-linkage, spiro-[indole-thiazolidine]-2,4’-diones, 2-(2-oxo-chromenyl)-3-thiazolidinones, 2-pyrazolo-thiazolidineones, 2-imino-thiazolidine, and pyridine-based 5-amino-2-oxo-thiazolo[4,5-b] pyridine-6-carbonitriles has been described using various ILs. This review aims at the synthesis advancement in the assembly of TZs in ILs during 2012–2023, under various conditions such as reflux, stirring, solvent-free or microwave, and ultrasound irradiation conditions. Devoid of vapor pressure, and being recyclable, ILs are relatively eco-friendly, especially for inherently sustainable multi-component reactions (MCRs) that are atom-economic and are endowed with waste reduction attributes in terms of fewer manipulations.

使用离子液体作为绿色催化剂和介质合成噻唑烷：最新进展

噻唑烷（TZ）是一类重要的杂环化合物，具有多种药物和生物活性。由于我们对杂环化学和生物学的兴趣，以及在有机转化过程中对离子液体（ILs）的利用，本文讨论了在离子液体中制备 TZs 的最新进展，其中离子液体扮演着溶剂和催化剂的双重角色。文章介绍了使用各种离子态溶液制备各种类型的 TZs，即具有偶氮连接的 1,3-噻唑烷-4-酮、螺-[吲哚-噻唑烷]-2,4'-二酮、2-(2-氧代-色烯基)-3-噻唑烷酮、2-吡唑-噻唑烷酮、2-亚氨基-噻唑烷和吡啶基 5-氨基-2-氧代-噻唑并[4,5-b] 吡啶-6-甲腈。本综述旨在介绍 2012-2023 年期间，在回流、搅拌、无溶剂或微波和超声辐照等各种条件下，TZs 在 ILs 中组装的合成进展。由于不存在蒸汽压，且可回收利用，IL 相对来说是一种生态友好型材料，尤其适用于固有的可持续多组分反应 (MCR)。

期刊介绍： The Journal of Sulfur Chemistry is an international journal for the dissemination of scientific results in the rapidly expanding realm of sulfur chemistry. The journal publishes high quality reviews, full papers and communications in the following areas: organic and inorganic chemistry, industrial chemistry, materials and polymer chemistry, biological chemistry and interdisciplinary studies directly related to sulfur science. Papers outlining theoretical, physical, mechanistic or synthetic studies pertaining to sulfur chemistry are welcome. Hence the target audience is made up of academic and industrial chemists with peripheral or focused interests in sulfur chemistry. Manuscripts that truly define the aims of the journal include, but are not limited to, those that offer: a) innovative use of sulfur reagents; b) new synthetic approaches to sulfur-containing biomolecules, materials or organic and organometallic compounds; c) theoretical and physical studies that facilitate the understanding of sulfur structure, bonding or reactivity; d) catalytic, selective, synthetically useful or noteworthy transformations of sulfur containing molecules; e) industrial applications of sulfur chemistry; f) unique sulfur atom or molecule involvement in interfacial phenomena; g) descriptions of solid phase or combinatorial methods involving sulfur containing substrates. Submissions pertaining to related atoms such as selenium and tellurium are also welcome. Articles offering routine heterocycle formation through established reactions of sulfur containing substrates are outside the scope of the journal.
