Wang, Yan published the artcileTransition Metal-Free Synthesis of Pinacol Arylboronate: Regioselective Boronation of 1,3-Disubstituted Benzenes, Safety of 2-(2-Chloro-6-methoxyphenyl)-4,4,5,5-tetramethyl-1,3,2-dioxaborolane, the main research area is pinacol arylboronate preparation; regioselective boronation disubstituted benzene.

The regioselective synthesis of pinacol arylboronate has been achieved from 1,3-disubstituted benzene through directed ortho-metalation (DoM)-borylation sequence. A wide range of substituents and borylating reagents were investigated. In situ lithiation and subsequent boronation predominantly occurred at the ortho-position to afford the desired products in moderate yields.

A series of 3-(phenoxy-phenyl-methyl)-pyrrolidine analogs were discovered to be potent and balanced norepinephrine (NE) and serotonin (5-hydroxytryptamine, 5-HT) reuptake inhibitors. Several of these compounds were identified to have suitable in vitro pharmacokinetic properties for an orally dosed and CNS-targeted drug. Compound 39b, in particular, was identified as a potent NET and SERT reuptake inhibitor (NSRI) with minimal off-target activity and demonstrated robust efficacy in the spinal nerve ligation model of pain behavior.

Dhungana, Roshan K. published the artcileNi-catalyzed regioselective 1,2-dialkylation of alkenes enabled by the formation of two C(sp3)-C(sp3) bonds, Application In Synthesis of 886496-91-9, the main research area is alkene regioselective dialkylation benzyl halide alkylzinc reagent nickel catalysis.

The authors disclosed a Ni-catalyzed vicinal difunctionalization of alkenes with benzyl halides and alkylzinc reagents, which produces products with two new alkyl-alkyl bonds. This alkene dialkylation is effective in combining secondary benzyl halides and secondary alkylzinc reagents with internal alkenes, which furnishes products with three contiguous all-carbon secondary stereocenters. The products can be readily elaborated to access complex tetraene, benzosuberene, and bicyclodecene cores. The reaction also features as the most efficient alkene difunctionalization process to date with catalyst loadings down to 500 ppm and the catalytic turnover number (TON) and turnover frequency (TOF) registering up to 2 x 103 and 165 h-1 at rt, resp.

A novel approach for the synthesis of polysubstituted 3-amino pyrroles via palladium-catalyzed three-component tandem reaction was developed. The procedure constructs various polysubstituted 3-amino pyrroles, e.g. I, with moderate to excellent yields under mild reaction conditions with assembly efficiency, readily available starting materials, and good functional group tolerance. Furthermore, this process was successfully applied to the synthesis of different 3-phenyl-1,4-dihydropyrrolo[3,2-b]indole derivatives via an intramol. Buchwald-Hartwig cross-coupling reaction in two steps.

Liu, Zhenghui published the artcileSmall organic molecules with tailored structures: initiators in the transition-metal-free C-H arylation of unactivated arenes, Formula: C6H3ClFI, the main research area is biaryl preparation; unactivated arene aryl iodide arylation methylaminophenyl methanol catalyst.

In this article, an optimized catalytically active mol., (2-(methylamino)phenyl)methanol, was designed. A broad range of aryl iodides RI (R = 2-fluorophenyl, thiophen-3-yl, pyridin-4-yl, etc.) could be converted into the corresponding arylated products RR1 (R1 = Ph, 4-methylphenyl) at 100°C over 24 h with good to excellent yields. Mechanistic experiments verified that radicals participated in this catalytic transformation and that the cleavage of the aromatic C-H bond was not the rate determining step. A K+ capture experiment by 18-crown-6 emphasized the significance of the cation species of the strong base. Fourier transform IR spectroscopy proved that the catalytic system was activated by the hydrogen bonds between small organic mols. and tBuOK. Also, a clear mechanism was proposed. This transition-metal-free method affords a promising system for efficient and inexpensive synthesis of biaryls via a user-friendly approach, as confirmed by scale-up experiments

Tsvelikhovsky, Dmitry published the artcileConcise Palladium-Catalyzed Synthesis of Dibenzodiazepines and Structural Analogues, COA of Formula: C7H3BrClF3O, the main research area is dibenzodiazepine dibenzooxazepine preparation palladium copper catalyzed cross coupling; aniline dihaloarene reactant palladium catalyzed coupling diarylamine preparation; diarylamine reactant palladium catalyzed cross coupling dibenzodiazepine preparation; phenol dihaloarene reactant palladium catalyzed coupling diarylether preparation; diarylether reactant palladium catalyzed cross coupling dibenzodiazepine preparation.

A general and highly efficient protocol for the synthesis of dibenzodiazepines and their structural analogs is reported. In the presence of catalytic quantities of palladium, readily accessible precursors are cross-coupled with ammonia and then spontaneously undergo an intramol. condensation to form the corresponding dibenzodiazepines, e.g. I, in one step. This new strategy is applicable to the construction of a wide variety of dibenzooxazepines, e.g. II, and other structurally related heterocycles, e.g. III.

Shen, Chaoren published the artcilePalladium-Catalyzed Carbonylative Four-Component Synthesis of Thiochromenones: The Advantages of a Reagent Capsule, Safety of 4-Chloro-2-fluoroiodobenzene, the main research area is four component reaction fluoroiodobenzene phenylacetylene carbonylative palladium catalyst; thiochromenone preparation; carbonylation; multicomponent reactions; palladium catalysis; thiochromenones.

Multicomponent reactions, especially those involving four or even more reagents, have been a long-standing challenge because of the issues associated with balancing reactivity, selectivity, and compatibility. Herein, we demonstrate how the use of a reagent capsule provides straightforward access to synthetically valuable thiochromenone derivatives by a palladium-catalyzed carbonylative four-component reaction. To the best of our knowledge, this is the first example of applying a capsule to prevent catalyst poisoning and undesired side reactions of the multicomponent reaction.
