Hyperactive magnetically separable nano-sized MgFe₂O₄ catalyst for the synthesis of several five- and six-membered heterocycles was written by Bansal, Shobha;Kumar, Yogendra;Das, Dipak Kumar;Singh, Prabal Pratap. And the article was included in Chemistry & Chemical Technology in 2019.Recommanded Product: 40230-24-8 This article mentions the following:

MgFe₂O₄ nanoparticle ferrites were synthesized by combustion technique using pure ferric nitrate and magnesium nitratecarbonate. The magnetically separable MgFe₂O₄ MNP’s were found to be hyper active catalyst for the synthesis of a wide range of biol. active five and six-membered heterocyclic moieties at refluxing conditions. Reaction times were lowest in comparison to all reported in literature with excellent yields. Strong electron pull of Fe³⁺ was responsible for its hyper activity, which was substantiated by substitution of Fe³⁺ by other trivalent metal ions. Mg²⁺ contain a unique role because replacement of Mg²⁺ has poor catalytic activity. The developed protocol was efficiently utilized for the synthesis of a series of substituted mono/bis pyrimidines, pyrimidin-2-ol, pyrimidin-2-thiol, pyrazoles and isoxazoles by condensing monochalcones/1,4-bischalcones with various bis-nucleophiles in the presence of catalytic amount of heterogenous magnetic MgFe₂O₄ nanoparticles. The structure of these synthesized compounds was determined by FTIR, ¹H, ¹³C and mass spectra. The catalyst was removed easily from reaction mixture by using a simple external magnet. Nanoparticles of ferrite were recovered and reused with no appreciable change in the activity even after the five runs. Nanoparticles were characterized by XRD, TEM and IR spectroscopy. In the experiment, the researchers used many compounds, for example, 4,6-Diphenylpyrimidin-2-amine (cas: 40230-24-8Recommanded Product: 40230-24-8).

Oxalic acid catalysed chromium(VI) oxidation of some 2-amino-4,6-diarylpyrimidines was written by Meenakshisundaram, S. P.;Gopalakrishnan, M.;Nagarajan, S.;Sarathi, N.. And the article was included in Catalysis Communications in 2007.SDS of cas: 40230-24-8 This article mentions the following:

Some 2-amino-4,6-diarylpyrimidines (APM), synthesized from chalcones and guanidine hydrochloride in presence of alkali by microwave irradiation in solvent-free conditions, were subjected to oxidation with chromium(VI)-oxalic acid complex (Cr(VI)-Oxa) in highly acidic solutions Oxalic acid (Oxa) offers the reaction a more favorable pathway and in the absence of oxalic acid the reaction is sluggish. The depletion of chromium(VI) shows a complicated kinetics involving a fast reaction to about 35% consumption followed by a slow one. Low dielec. constant of the medium facilitates the reaction. The investigations with 2-amino-6-(4-nitrophenyl)- 4-phenylpyrimidine and 2-amino-6-(4-methoxyphenyl)-4-phenylpyrimidine reveal that, irresp. of the nature of the substituents, the rates are higher than for the parent. APM is catalytically converted to the unusual product 3-hydroxy-1,3-diphenyl-propan-1-one. Consideration of the kinetic behaviors under different exptl. conditions and the product assignment provide valuable mechanistic insight into the system studied.

A series of 2-(2,6-dihalophenyl)-3-(substituted pyrimidinyl)-1,3-thiazolidin-4-ones were designed on the prediction of quant. structure-activity relationship (QSAR) studies, synthesized, and evaluated as HIV-1 reverse transcriptase inhibitors. Our attempts in correlating the identified mol. surface features related properties for modeling the HIV-1 RT inhibitory activity resulted in some statistically significant QSAR models with good predictive ability. The results showed that compounds 4m (I, R₁ = Cl) and 4n (I, R₁ = F) were highly active in inhibiting HIV-1 replication with EC₅₀ values in the range of 22-28 nM in MT-4 as well as in CEM cells with selectivity indexes of >10,000.
