Jiang, Ben-Jie published the artcileSynthesis of Quinolines and 2-Functionalized Quinolines by Difluorocarbene Incorporation, Product Details of C7H6N2, the main research area is functionalized quinoline chemoselective preparation; quinoline preparation.

A general method was developed to allow de novo construction of quinolines I [R = Me, cyclopropyl, Ph, etc.] and C2-functionalized quinolines II [R1 = Me, cyclopentyl, Ph; R2 = Ph, Bn, 1-naphthyl, etc.; R3 = H, Me] from ortho-alkenyl anilines in the presence of a difluorocarbene precursor. This method exploited a crucial reactivity of in-situ generation of isocyanides from condensation of primary aniline with difluorocarbene. Subsequent α-addition of isocyanide by neighboring alkenyl group constructs the quinoline ring. Furthermore, when a combination of difluorocarbene precursor and Se are present, selenoisocyanate intermediates were tentatively generated that upon nucleophilic addition by ortho-alkenyl produce 2-SeH quinolines. In the presence of a second nucleophile such as anilines, competing nucleophilic addition of anilines to the selenoisocyanate was preferred, generating selenourea intermediate. Further nucleophilic addition of the ortho-alkenyl to selenourea followed by elimination of H2Se produces 2-aminoquinolines. This allows one-step multi-component modular preparation of various C2-functionalized quinolines from readily available starting compounds This method showed good yields, scope and chemoselectivity. It was operationally convenient and friendly without manipulating unpleasant isocyanides. The difluorocarbene-enabled primary amine to isocyanide conversion may be exploited to develop other interesting reactions.

Bera, Srikrishna published the artcileEnantioselective C(sp3)-C(sp3) cross-coupling of non-activated alkyl electrophiles via nickel hydride catalysis, HPLC of Formula: 100-70-9, the main research area is enantioselective sp3 hybridized carbon cross coupling nickel catalyzed.

Cross-coupling of two alkyl fragments is an efficient method to produce organic mols. rich in sp3-hybridized carbon centers, which are attractive candidate compounds in drug discovery. Enantioselective C(sp3)-C(sp3) coupling is challenging, especially of alkyl electrophiles without an activating group (aryl, vinyl, carbonyl). Here, we report a strategy based on nickel hydride addition to internal olefins followed by nickel-catalyzed alkyl-alkyl coupling. This strategy enables the enantioselective cross-coupling of non-activated alkyl halides with alkenyl boronates to produce chiral alkyl boronates. Employing readily available and stable olefins as pro-chiral nucleophiles, the coupling proceeds under mild conditions and exhibits broad scope and high functional-group tolerance. Applications for the functionalization of natural products and drug mols., as well as the synthesis of chiral building blocks and a key intermediate to (S)-(+)-pregabalin, are demonstrated.

Karaki, Fumika published the artcileCatalyst-free photooxidation reaction from 1,4-dihydropyridazine to pyridazine under air, Related Products of nitriles-buliding-blocks, the main research area is tetrazine strained alkene inverse electron Dielse Alder reaction photooxidation; pyridazine preparation.

In the inverse electron-demand Diels-Alder (iEDDA) reactions between tetrazines and strained alkenes, a mixture of 1,4-dihydropyridazine isomers are formed first, and they are then oxidized to pyridazines. Although the products of these related oxidation processes converge as pyridazines, the oxidation rate was quite low with some substrates. In this study, 1,4-dihydropyridazines formed in the iEDDA reactions were oxidized to pyridazines by simply irradiating with an UV light under an air atm. Exptl. results implied that singlet oxygen was formed in the course of the reactions to oxidize the 1,4-dihydropyridazine mols.

An umpolung addition of dicyanobenzene to α,β-unsaturated alkenes has been developed using an electroreductive strategy. This electrochem. protocol is well compatible with a broad range of conventionally challenging substrates, including α,β-unsaturated esters, nitriles and trisubstituted enones. Moreover, good to excellent regioselectivities are observed in the reaction of cinnamates with dicyanobenzene. Synthetic utility of this electrochem. approach is further demonstrated by direct late-stage functionalization of (S)-verbenone and 16-dehydropregnenolone acetate.
