Li, Tao published the artcileThree-Component Minisci Reaction with 1,3-Dicarbonyl Compounds Induced by Visible Light, Synthetic Route of 63131-30-6, the main research area is quinoline preparation visible light Minisci dicarbonyl vinyl ether heterocycle; isoquinoline preparation visible light Minisci dicarbonyl vinyl ether heterocycle.

A three-component Minisci reaction coupling of 1,3-dicarbonyl compounds with vinyl ethers and quinolines or isoquinolines under visible light is developed. The 1,3-dicarbonyl compound undergoes single-electron oxidation to afford an electrophilic 1,3-dicarbonyl radical under visible light irradiation Due to the polarity of the free radical, the electrophilic radical adds to the electron-rich olefin to afford the nucleophilic radical. It coupled with the heteroarene to afford the three-component coupling products.

Ton, Thi My Uyen published the artcileCopper(II) triflate catalyzed amination and aziridination of 2-alkyl substituted 1,3-dicarbonyl compounds, Synthetic Route of 63131-30-6, the main research area is aziridine preparation; aminomethyl dicarbonyl compound preparation; alkyl dicarbonyl compound aziridination amination copper triflate catalyst.

A method to prepare α-acyl-β-amino acid and 2,2-diacyl aziridine derivatives efficiently from Cu(OTf)2 + 1,10-phenanthroline (1,10-phen)-catalyzed amination and aziridination of 2-alkyl substituted 1,3-dicarbonyl compounds with PhI=NTs is described. By taking advantage of the orthogonal modes of reactivity of the substrate through slight modification of the reaction conditions, a divergence in product selectivity was observed In the presence of 1.2 equiv of the iminoiodane, amination of the allylic C-H bond of the enolic form of the substrate, formed in situ through coordination to the Lewis acidic metal catalyst, was found to selectively occur and give the β-aminated adduct. On the other hand, increasing the amount of the nitrogen source from 1.2 to 2-3 equiv was discovered to result in preferential formal aziridination of the C-C bond of the 2-alkyl substituent of the starting material and formation of the aziridine product.

Forschner-Dancause, Stephanie published the artcileQuorum sensing inhibition and structure-activity relationships of β-keto esters, Recommanded Product: Ethyl 3-(4-iodophenyl)-3-oxopropanoate, the main research area is keto ester structure quorum sensing inhibition; Vibrio harveyi; quorum sensing inhibition; β-keto esters.

A panel of 19 β-keto ester analogs was tested for the inhibition of bioluminescence (a quorum sensing-controlled phenotype) in the marine pathogen Vibrio harveyi. Initial screening demonstrated the need of a Ph ring at the C-3 position for antagonistic activity. Further additions to the Ph ring with 4-substituted halo groups or a 3- or 4-substituted methoxy group resulted in the most active compounds with IC50 values ranging 23-53μM. The compounds addnl. inhibit green fluorescent protein production by Escherichia coli JB525. Evidence is presented that aryl β-keto esters may act as antagonists of bacterial quorum sensing by competing with N-acyl homoserine lactones for receptor binding. Expansion of the β-keto ester panel will enable us to obtain more insight into the structure-activity relations needed to allow for the development of novel anti-virulence agents.

Menozzi, Giulia published the artcileRational design, synthesis and biological evaluation of new 1,5-diarylpyrazole derivatives as CB1 receptor antagonists, structurally related to rimonabant, Safety of Ethyl 3-(4-iodophenyl)-3-oxopropanoate, the main research area is diarylpyrazole rimonabant regioisomer preparation mol modeling cannabinoid receptor antagonism.

Among cannabinoid type-1 (CB1) receptor antagonists, those developed around the 1,5-diarylpyrazole scaffold of rimonabant (I, Acomplia) are the most extensively investigated. In recent years, many SAR and QSAR reports on this topic have been published, focusing on the substitution and orientation of the N1 and C5 aryl functionalities and on the substituents at the 3-carboxamide position. In this context, the purpose of our study was to design and synthesize a set of 1-(2,4-dichlorophenyl)-5-arylpyrazoles strictly related to rimonabant, but with the hydrazide/amide group shifted from position 3 to position 4 of the pyrazole scaffold. The synthesized compounds were evaluated in vitro for their affinity on human CB1 and CB2 (cannabinoid type-2) receptors. Computational studies, performed both in the design step and after biol. assays, contributed to rationalize the obtained results in terms of specific mol. interactions between antagonists and the human CB1 receptor.

Song, Gui-Ting published the artcileSynthesis of monofluorooxazoles with quaternary C-F centers through photoredox-catalyzed radical addition of methylene-2-oxazolines, Application In Synthesis of 63131-30-6, the main research area is monofluorooxazole quaternary carbon fluorine center preparation; bromo fluoro oxoarylpropionate preparation methylene oxazoline radical addition photocatalyst.

A novel photoredox-catalyzed radical addition of methylene-2-oxazolines I (R = Ph, hexyl, cyclohexyl, thiophen-2-yl, etc.) has been developed under visible light irradiation to synthesize monofluorooxazoles II (R1 = Ph, furan-2-yl, 3-methylphenyl, etc.) with a quaternary carbon center using 2-bromo-2-fluoro-3-oxo-3-phenylpropionates R1C(O)C(F)(Br)C(O)OEt as radical source. This method with a simple protocol, scalability and high yield offers a facile path to get diverse monofluorinated oxazoles II with quaternary C-F centers, which are a class of highly valuable motifs and synthons.

Watson, Rebecca B. published the artcileIron(III) Chloride Catalyzed Formation of 3,4-Dihydro-2H-pyrans from α-Alkylated 1,3-Dicarbonyls. Selective Synthesis of α- and β-Lapachone, Safety of Ethyl 3-(4-iodophenyl)-3-oxopropanoate, the main research area is dihydropyran preparation iron chloride catalyzed cyclization; lapachone synthesis iron chloride catalyzed cyclization.

A mild, catalytic method for the synthesis of 3,4-dihydro-2H-pyrans is described. The FeCl3-catalyzed transformation of aryl- and alkyl β-diketones enables synthetic access to functionalized pyran core structures incorporated in many natural products and biol. active target structures. The method represents a mild alternative to currently available reaction protocols relying on stoichiometric reagents and harsh reaction conditions. This FeCl3-catalyzed transformation has enabled the selective synthesis of α-lapachone in two synthetic transformations and subsequently β-lapachone in three synthetic transformations, which is currently undergoing clin. trials as a potent anticancer agent.

Wang, Heng-Yen published the artcileRegioselective synthesis of 2,3,4- or 2,3,5-trisubstituted pyrroles via [3,3] or [1,3] rearrangements of O-vinyl oximes, Application In Synthesis of 63131-30-6, the main research area is pyrrole derivative regioselective synthesis; vinyl oxime isomerization sigmatropic rearrangement Ir catalyst.

The regioselective synthesis of 2,3,4- or 2,3,5-trisubstituted pyrroles e. g., I has been achieved via [3,3] and [1,3] sigmatropic rearrangements of O-vinyl oximes, resp. Iridium-catalyzed isomerization of easily prepared O-allyl oximes enables rapid access to O-vinyl oximes. Optimization and scope of the O-allyl oxime isomerization and subsequent pyrrole formation are discussed and mechanistic pathways are proposed. The regioselectivity of pyrrole formation can be controlled by either the identity of the α-substituent or through the addition of an amine base. When enolization is favored, a [3,3] rearrangement followed by a Paal-Knorr cyclization provides a 2,3,4-trisubstituted pyrrole; when enolization is disfavored, a [1,3] rearrangement occurs prior to enolization to produce a 2,3,5-trisubstituted pyrrole after cyclization. Conditions are provided for selecting either the [3,3] rearrangement or the [1,3] rearrangement product with β-ester O-allyl oxime substrates.
