Thiazoloquinolines are an important class of heterocyclic molecules having a wide variety of biological activities. Since the first synthesis of this fused heterocyclic ring system in 1937, quite a good number of research works have been accomplished in designing and achieving the synthesis of various substituted thiazoloquinolines. These molecules possess diverse structural features and bioactive potentials. A thorough survey of literature, available in this field, clearly indicates that there are certain fused thiazoloquinolines whose syntheses have been largely dealt with while the synthesis of some other fusion pattern remains comparatively less explored. The objective of this review is to present a concise overview of the methods towards the synthesis of thiazoloquinolines in a chronological manner.

“…Some thiazoloquinoline derivatives have been described as potential anti-inflammatory, antispasmodics, probes for fluorescent molecules, and precursors of symmetrical cyanines . Moreover, thiazoloquinoline is also found to be active in the production of polymethine dyes and as spectral sensitizers of silver halide emulsions …”

Metal-Free One-Pot Four-Component Cascade Annulation in Ionic Liquids at Room Temperature: Convergent Access to Thiazoloquinolinone Derivatives

2018

An efficient, eco-friendly, and highly convergent one-pot route to privileged thiazoloquinolinone derivatives has been developed via four-component cascade coupling (4CCC) of α-enolic dithioesters, cysteamine/2-aminothiophenols, aldehydes, and cyclic 1,3-diketones in recyclable [EMIM][EtSO] ionic liquid at room temperature for the first time. The reaction proceeds via a N,S-acetal formation, Knoevenagel condensation, aza-ene reaction, imine-enamine/keto-enol tautomerization, and intramolecular N-cyclization cascade sequence. The merit of the protocol is highlighted by its efficacy of forming consecutive five new bonds (two C-C, two C-N, and one C-S) and two rings with all reactants being efficiently utilized. The operational simplicity, sustainability, mild conditions, excellent yields, tolerance of wide functional groups, and avoidance of expensive/toxic reagents are additional attributes to this domino four-component protocol. Notably, the products were easily separated from the ionic liquid, and thus the ionic liquid obtained was reused four times without considerable loss of any activity.

“…14,15 They also are used in production of polymethine dyes and as spectral sensitizers of silver halide emulsions. 16 In this study, we report MNPs-L-leucine as a new catalyst for the synthesis of thiazoloquinolines through the fourcomponent reaction of a-enolicdithioesters (1), cysteamine (2), aromatic aldehydes (3), and dimedone (4) under thermal solvent-free conditions (Scheme 1). Fe 3 O 4 nanoparticles were facilely synthesized by a chemical coprecipitating method.…”
