“…Triethylamine catalysed one pot synthesis of quinoline derivatives was reported by Moloi and team . Quinoline derivatives were synthesised by the reaction of aromatic aldehydes, malononitrile, 5,5‐dimethylcyclohexane‐1,3‐dione and ammonium acetate in ethanol solvent at room temperature (Scheme ).…”

Microwave (MW) assisted multicomponent reactions (MCRs) provide facile and expeditious procedures for the synthesis of several diversely functionalised molecules. Significant enhancement in selectivity, purity and reproducibility is offered by this process. Shorter reaction times as well as higher product yield are attained efficiently using MW assisted MCRs. The present review focuses on the developments in this field covering literature from 2013–2019 and the topic is categorised based on the final products obtained.

We report a novel ecofriendly cascade reaction for the synthesis of arylsulfonyl-4H-pyran derivatives by a three component fusion reaction of chosen aldehyde, dimedone and phenylsulphonyl acetonitrile at room temperature using ruthenia doped fluorapatite (RuO 2 /FAp) as recyclable catalyst. Different percentages of RuO 2 /FAp materials were prepared and characterized by FT-IR, P-XRD, BET, SEM-EDX and TEM analysis. Attractive features of the synthetic approach are operational simplicity, cost-effectiveness, short reaction time and excellent yields. Easily recoverable and reusable catalyst material without any deceptive loss of catalytic activity up to seven cycles is additional benefit.

“…[24][25] Several homogeneous and heterogeneous catalysts have been employed for the synthesis of substituted hexahydroquinolines derivatives. Among them, the synthesis using nano-ZnO/ultrasound nano-Fe 3 O 4 , [26] AcOH, [27] K 2 CO 3 , [28] triethylamine, [29] Fe 3-x Ti x O 4 @SPDETATSA (N-(3-silyl propyl) diethylene triamine N,N',N''-tri-sulfonic acid immobilized on Fe 3-found to act as laser dyes due to electron delocalization and exhibit fluorescence and laser activity. [33,34] The effectiveness of lasing is dependent upon the substituents at C-9 and N-10 of the acridine chromophore.…”

An efficient, straight forward, eco‐friendly procedure for the synthesis of biologically active hexahydroquinoline derivatives and hexahydroacridine‐1,8‐diones has been designed using a novel bio‐degradable heterogeneous catalyst, sulphonated rice‐husk (SRH). SRH provides high density of acid groups making it different from conventional solid acids containing single acid groups. We report an efficient protocol for the synthesis of hexahydroquinolines and hexahydroacridine‐1,8‐diones using this carbon based acid catalyst (SRH) in solvent free and greener solvent respectively. Moreover, operational simplicity, greener reaction condition, reusability of the catalyst, excellent yield (upto 98 %) are the fundamental features of this protocol. The metal free catalyst was characterised using different spectroscopic techniques FTIR, SEM, EDX, Powder XRD, ICP‐AES.
