A concise review of articles published in the last five years devoted to the synthesis of 2-thioxoimidazolidin-4-one derivatives, including those with certain types of biological activity, is presented.

This microreview discusses the latest examples (2012–2022) of the synthesis of pyrazolo[3,4-d]-thiazoles, pyrazolo[4,3-d]thiazoles, pyrazolo[4,3-b][1,4]thiazines, and pyrazolo[3,4-b][1,4]-thiazines via two main approaches: annulation of the pyrazole ring to the thiazole or thiazine ring and, conversely, annulation of the thiazole or thiazine ring to the pyrazole ring.
An effective one-pot three-component protocol for the synthesis of polysubstituted thiazole derivatives is reported. The reaction proceeds between arylglyoxals, thiosemicarbazones, and acetylacetone or ethyl acetoacetate in ethanol as solvent and in the presence of acetic acid as catalyst.
This microreview summarizes the data published over the last 10 years on the synthesis of bi(poly)- and macrocyclic compounds starting from trans-1,2-diaminocyclohexane. Some of these compounds may find use as drugs, catalysts for a number of important chemical transformations, or new organic porous materials.
