An In‐Depth Review on Recent Progress in Synthetic Approaches and Biological Activities of Thiazol‐2( <i>3H</i> )‐Imine Derivatives

Abstract This review presents the in‐dept analysis of the synthetic approaches towards thiazol‐2( 3H )‐imine and embarks at its various biological properties published during 2000 to 2023. The most important method of synthesis involves the reaction of substituted thioureas and α‐halo carbonyl compounds, and condensation and nucleophilic addition of 2‐amino‐1,3‐thiazoline with aldehydes. Additionally, isothiocyanate‐based multicomponent synthesis, and α‐nitroepoxides have been proved as benign precursors for this motif. Several eco‐friendly and solvent‐free synthesis from diazonium salts, acetylenes, tertiary enaminones and thiosemicarbazides have also been reported. This epitome is a unique combination of synthetic methods as well as biological activities like anti‐inflammatory, anti‐bacterial, anti‐cancer, anti‐leishmanial, anti‐microbial, herbicidal, anti‐HIV, and may be a valuable tool for researchers to tailor the synthetic procedures according to specific target structures and applications. Moreover, this review enlightens the applications of thiazol‐2( 3H )‐imine as platelet GPIIB/IIIA receptor antagonists, alkaline phosphatase inhibitors, neurodegenerative drug Pifithrin‐α analogues, and skin whitening agents.
