New Twists in the Chemistry of Thioureas: 1,3‐Thiazolidines as a Vector of Sustainability.

This study introduces a sustainable and pioneering cascade synthesis of 1,3‐thiazolidine derivatives under eco‐friendly conditions. The methodology transcends traditional approaches yielding complex novel compounds with unique N,S‐heterocyclic structures. By operating at room temperature, utilizing green solvents, and minimizing excess of reactants, this procedure offers an innovative pathway for sustainable chemical development. Notably, this method not only prioritizes sustainability but also delivers high‐purity products with exceptional yields. The simplicity of the process, requiring only a simple filtration and featuring short reaction times, underscores its efficiency and utility. [ABSTRACT FROM AUTHOR]
