Wu, Xiang published the artcileGold-catalyzed cyclization of 1-(2′-azidoaryl)propynols: synthesis of polysubstituted 4-quinolones, Name: 2-Aminobenzonitrile(Flakes or Chunks), the main research area is quinolone preparation; azidoaryl propynol cyclization gold catalyst.

An unprecedented gold-catalyzed procedure for the synthesis of polysubstituted 4-quinolones I (R1 = C6H5, 4-NCC6H4, 4-FC6H4, etc.; R2 = H, 7-Me, 6-Br, etc.) from 1-(2′-azidoaryl)propynols II is described. The reaction underwent an intramol. nucleophilic attack of the azide group to the Au-activated triple bonds in a 6-endo-dig manner and subsequent gold-assisted expulsion of N2 to furnish an α-imino gold carbene intermediate, which triggers a 1,2-carbon migration and finally is converted to 2,3-disubstituted 4-quinolone.

Tsutsumi, Hiroyuki published the artcileMolecular capture using the precipitate of creaming-down by (-)-epigallocatechin-3-O-gallate, Product Details of C6H4N2, the main research area is epigallocatechin gallate chloropyrimidine crystal structure hydrogen bond mol capture; (�-epigallocatechin-3-O-gallate; 2-chloropyrimidine; X-ray crystallographic analysis; creaming-down; quantitative 1H-NMR.

An aqueous solution of equimol. amounts of 2-chloropyrimidine and (-)-epigallocatechin 3-O-gallate (EGCg) afforded a colorless block crystal, which was determined to be a 2 : 2 complex of 2-chloropyrimidine and EGCg by X-ray crystallog. anal. The 2 : 2 complex was formed by the cooperative effect of three intermol. interactions, π-π and CH-π interactions, and intermol. hydrogen bonds. Upon formation of the 2 : 2 complex, a 2-chloropyrimidine mol. was captured by a hydrophobic space formed by the three aromatic rings of A, B, and B’ rings of two EGCg mols. The mol. capture abilities of various heterocyclic compounds using EGCg were evaluated by ratio of the heterocyclic compounds included in the precipitates of complex of EGCg to the heterocyclic compounds used. The amount of the heterocyclic compounds was measured by an integrated value of corresponding proton signals in the quant. 1H-NMR spectrum.

Tian, Jun-Jie published the artcileIntramolecular Cyclizations of Vinyl-Substituted N,N-Dialkyl Arylamines Enabled by Borane-Assisted Hydride Transfer, Quality Control of 1885-29-6, the main research area is arylamine dialkyl vinyl borane hydride transfer cyclization catalyst; tetrahydrobenzoquinoline preparation.

Catalytic amounts of B(C6F5)3 have been found to be able to promote the intramol. cyclization of vinyl-substituted N,N-dialkyl arylamines to afford nitrogen-containing heterocycles I (R = Me, Bn, n-pentyl; R1 = H, Ph, n-Bu; R2 = Ph, 4-EtC6H4, 3-MeC6H4, Me, n-Pr, etc.). Our mechanistic studies indicate the reaction is initiated by abstraction of an α-hydride from an N-alkyl substituent by B(C6F5)3, which is followed by cyclization, and is concluded by delivery of the hydride to the cyclic cationic intermediate. The dual roles of B(C6F5)3, first as an oxidant and then as a hydride-carrying reductant, have enabled a rare redox-neutral cyclization process between a sp3 carbon and an electron-rich olefin without using a transition metal or an external oxidant.

A metal-free silyl-pyridylation of alkenes using silyl boronates and B2pin2 through a pyridine-mediated B-interelement activation was demonstrated, which provides a practical strategy for a variety of C4-silylalkylated pyridines. DFT calculations and control experiments show that the reaction proceeds through a silyl radical addition/radical-radical coupling sequence. This protocol features a broad substrate scope and excellent functional group compatibility, and thus it showcases great potential in the late-stage modification of bioactive mols.
