“…Sandaroos et al [ 68 ] have synthesised tetrahydro furopyran ( 48 ) scaffolds using iron triflate nanocatalyst (Fe(OTf) 3 ). It was explored as a catalyst for MCR system consisting of aromatic aldehyde ( 46 ), tetronic acid ( 47 ) and malononitrile ( 3 ) in the presence of acetonitrile.…”

Pyrans are one of the most significant skeletons of oxygen-containing heterocyclic molecules, which exhibit a broad spectrum of medicinal applications and are constituents of diverse natural product analogues. Various biological applications of these pyran analogues contributed to the growth advances in these oxygen-containing molecules. Green one-pot methodologies for synthesising these heterocyclic molecules have received significant attention. This review focuses on the recent developments in synthesising pyran ring derivatives using reusable catalysts and emphasises the multicomponent reaction strategies using green protocols. The advantages of the catalysts in terms of yields, reaction conditions, and recyclability are discussed.

“…[39] An efficient synthesis of functionalized 4H-fluro [3,4-b]pyran by multicomponent reaction using iron(III) triflate as catalyst had also been reported. [40] Fe(III) catalysed Suzuki biaryl crosscoupling reaction between alkyllithium-activated aryl pinacol boronic esters and N-pyrrole amide and related directing groups on the aryl halide substrates is feasible with replacement of costly palladium catalyst by cheap iron. [41] Iron-based catalysts are efficiently used in Fischer-Tropsch synthesis, methanation of CO 2 , electrochemical synthesis of ammonia directly from N 2 and water and block copolymerization of epoxide.…”

Catalytic processes are indeed greener modification as they completes in much shorter time with minimizing the need of external energy source with atom economy and high selectivity. In this article we presented a short review on utlisation of different catalysts such as ionic liquids, transition metal ions, nano particles, surfactants, amino acids etc. for C‐C coupling reactions to oxidation reactions. Stereoselective and regioselective transformations are also carried out using catalyst in organic synthesis. Use of catalyst in rate enhancement of oxidation reaction is of immense interest and a surplus rate increment is obtained by use of promoters.

“…Iron triflate Fe(OTf)3 is a strong Lewis acid because the ferric ion has an empty 3d orbit and trifluoromethylsulfonates are strongly electronwithdrawing. Indeed, the triflate anion is both weakly nucleophilic and coordinating, rendering the metal counterion more cationic and thus a stronger Lewis acid [13]. It can activate the carbonyl group of carbonyl compounds, facilitating condensation between aniline, benzaldehyde and pyruvic acid to produce 2-phenilquinoline-4-carboxyluic acid compound.…”

Iron (III) trifluoromethanesulfonate [Fe (OTF)3] has been proven to be an effective catalyst in the synthesis of 2-phenylquinoline-4-carboxylic acid by the Doebner reaction using one-pot pyruvic acid, aniline, and benzaldehyde. This method shows attractive characteristics including concise one-pot conditions, high atom economy, very limited energy consumption, and the sequential catalytic process requires only a catalytic (15 mol%) amount of Fe (OTf)3 with short reaction periods (3 h) . Meanwhile, the catalyst was easily recovered from the reaction system and reused smoothly with only a little loss of activity.
