Semleit, Nina published the artcileControlling the Gold(I)-Catalyzed 1,5-Allenene Reaction: Construction of Fused Rings with Excellent Diastereoselectivity, HPLC of Formula: 151-10-0, the main research area is fused tricyclic compound preparation diastereoselective; allenene oxygen carbon nucleophile exo cyclization gold catalyst.

In the present study, the gold(I)-catalyzed reaction of 1,5-allenenes was controlled in such a way that instead of a [2+3] cycloaddition, a 5-exo-cyclization with the formation of a carbocation occurred. The latter could be trapped with both oxygen and carbon nucleophiles. In the investigated system, fused tricyclic frameworks I (R = Me; R1 = Me, Cl, Br, etc.; Nu = OMe, OEt, 2-furyl, etc.) with three contiguous stereocenters with excellent chemo- and diastereoselectivity in up to 95% yield were obtained.

Nobile, Enzo published the artcileC-H Electrophilic (phenylsulfonyl)difluoromethylation of (hetero)arenes with a newly designed reagent, Computed Properties of 151-10-0, the main research area is aniline heteroarene electrophilic phenylsulfonyl difluoromethylation benzenesulfonyl difluoromethyldibenzothiophenium triflate.

The synthesis of an original electrophilic difluoromethylating reagent was successfully achieved upon a straightforward protocol (3 steps). Like a Swiss army knife, this bench-stable reagent allowed the functionalization of various classes of compounds under mild and transition metal-free conditions. Hence, an efficient and operationally simple tool for the construction of C(sp2)-, C(sp3)- and S-CF2SO2Ph bonds was provided, expanding the chem. space of PhSO2CF2-containing mols. Late-stage functionalization of bioactive mols. and the synthesis of PhSO2CF2- and HCF2-analogs of Lidocaine were also successfully achieved.

Hirose, Yuuka published the artcileAromatic Halogenation Using N-Halosuccinimide and PhSSiMe3 or PhSSPh, Name: 1,3-Dimethoxybenzene, the main research area is arene aromatic halogenation halosuccinimide; haloarene preparation aromatic halogenation halosuccinimide.

We developed a mild aromatic halogenation reaction using a combination of N-halosuccinimide and PhSSiMe3 or PhSSPh. Less reactive aromatic compounds, such as Me 4-methoxybenzoate, were brominated with PhSSiMe3 or PhSSPh and N-bromosuccinimide in high yields. No reaction was observed in the absence of PhSSiMe3 or PhSSPh. This method is also applicable to chlorination reactions using N-chlorosuccinimide and PhSSPh.

The combination of Cu(OTf)2 and 1,10-phenanthroline in hexafluoroisopropanol (HFIP) was used for the green and regioselective amination of arenes with hydroxylamine-O-sulfonic acid, N-cyclohexylhydroxylamine-O-sulfonic acid, and O-(mesitylsulfonyl)-N-methylhydroxylamine at ambient temperature Under similar conditions, alkenes underwent diastereoselective aziridination with hydroxylamine-O-sulfonic acid, N-cyclohexylhydroxylamine-O-sulfonic acid, and O-(mesitylsulfonyl)-N-methylhydroxylamine at ambient temperature using CuCl2 and 1,10-phenanthroline as catalysts. The reactions provide alternatives to rhodium-catalyzed aziridinations and in some cases provide products with different regioselectivities than related rhodium- and iron-catalyzed reactions.

Hong Nguyen, Thi Anh published the artcileMetal-free, Direct Acetoxylation of Arenes, Recommanded Product: 1,3-Dimethoxybenzene, the main research area is arene acetic acid regioselective acetoxylation; aryl acetate preparation.

A metal-free, direct acetoxylation reaction using sodium nitrate under an anhydrous environment of trifluoroacetic acid, acetic acid and acetic anhydride was reported. Arenes (31 examples), with oxidation potentials (Eox, in V vs SCE) lower than benzene (2.48 V), were acetoxylated with good yields and regioselectivity. A stepwise, single electron-transfer mechanism was proposed.

De Smet, Gilles published the artcileSelective Nickel-Catalyzed Hydrodeacetoxylation of Aryl Acetates, Recommanded Product: 1,3-Dimethoxybenzene, the main research area is aromatic alc magnesium catalyst acetoxylation; aryl acetate preparation nickel catalyst chemoselective hydrodeacetoxylation green chem; anisole preparation; Aryl Acetates; C−O Bond Activation; Hydrodeacetoxylation; Nickel Catalysis; Renewable Resources.

Ni-catalyzed hydrodeacetoxylation of aryl acetates (Ar-OAc) with HBpin in a green carbonate solvent selectively delivered the corresponding deoxygenated arenes (ArH). The method was also applicable to highly challenging guaiacyl and syringyl acetates, leaving -OMe groups intact without arene reduction Renewable 4-propylguaiacol obtained from pine could also be transformed without significant loss in yield vs. oil derived feedstock. The observed chemoselectivity for Ar-OAc vs. ArO-Ac bond cleavage was rationalized based on mechanistic experiments and DFT calculations ArOH side-product formation was attributed to direct competitive Ni-catalyzed reduction of the C=O bond. Hydrodeacyloxylation of a set of aryl alkanoates featured interesting chemoselectivity with a dramatic influence of the length and structure of the alkyl chain on catalysis.

The substitution of highly diastereoenriched α-bromoarylacetates occurred in the presence of AgOTf, and the subsequent reduction afforded diverse 2,2-diarylethanols with high yields and enantioselectivities up to 99:1 er. In addition, the application of this asym. synthetic methodol. to the preparation of highly enantioenriched dihydrobenzofuran and indoline derivatives was demonstrated.

Zhao, Jiangui published the artcileSelective Rhodium-Catalyzed Hydroformylation of Terminal Arylalkynes and Conjugated Enynes to (Poly)enals Enabled by a π-Acceptor Biphosphoramidite Ligand, COA of Formula: C8H10O2, the main research area is aryl alkyne rhodium catalyst chemoselective stereoselective regioselective hydroformylation; alkenyne rhodium catalyst chemoselective stereoselective regioselective hydroformylation; polyenal preparation.

The hydroformylation of terminal arylalkynes and enynes offers a straightforward synthetic route to the valuable (poly)enals. However, the hydroformylation of terminal alkynes has remained a long-standing challenge. Herein, an efficient and selective Rh-catalyzed hydroformylation of terminal arylalkynes and conjugated enynes was achieved by using a new stable biphosphoramidite ligand with strong π-acceptor capacity, which afforded various important E-(poly)enals in good yields with excellent chemo- and regioselectivity at low temperatures and low syngas pressures.
