Arene cyclopropanation offers a direct route to higher-order, non-aromatic carbocycles; however, the inherent issue of dictating site selectivity has cumbered the development of novel intermolecular reactions that directly engage the arene pool. This paper describes a highly regio- and stereoselective, Rh-2[(S)-PTTL](4)-catalyzed arene cyclopropanation using alpha-cyanodiazoacetates to afford stable norcaradienes bearing three stereogenic centers, one of which is an all-carbon quaternary center. The enantioenriched norcaradienes served as tunable templates for further transformation into stereochemically dense, fused and bicyclic carbocycles containing transmutable functionality.

Functionalized beta-lactams are highly important motifs in synthetic chemistry. We report an efficient and novel approach to the synthesis of beta-lactams via a copper(i)-catalyzed cascade process involving C(benzyl)-H radical abstraction, intermolecular alkene addition, and intramolecular amination reaction. Variously substituted alkenes were synthesized from vinylacetic acid, leading to the corresponding beta-lactams in moderate to good yields. Preliminary studies indicate that the reaction undergoes a free radical mechanism via a Cu(i)/Cu(ii)/Cu(iii) catalytic cycle.

Unnatural alpha-amino acids are invaluable building blocks in synthetic organic chemistry and could upgrade the function of peptides. We developed a new mode for catalytic activation of amino acid Schiff bases, serving as a platform for highly congested unnatural alpha-amino acid synthesis. The redox active copper catalyst enabled efficient cross-coupling to construct contiguous tetrasubstituted carbon centers. The broad functional group compatibility highlights the mildness of the present catalysis. Notably, we achieved successive beta-functionalization and oxidation of amino acid Schiff bases to afford dehydroalanine derivatives bearing tetrasubstituted carbon. A three-component cross-coupling reaction of an amino acid Schiff base, alkyl bromides, and styrene derivatives demonstrated the high utility of the present method. The diastereoselective reaction was also achieved using menthol derivatives as a chiral auxiliary, delivering enantiomerically enriched alpha-amino acid bearing alpha,beta-continuous tetrasubstituted carbon. The synthesized highly congested unnatural alpha-amino acid could be derivatized and incorporated into peptide synthesis.

A highly efficient palladium-free homogeneous catalyst involving Ni(acac)(2)/2,6-bis(diphenylphosphino) pyridine ((Ph2P)(2)py)/CuI components was used for the Sonogashira cross-coupling reaction. The Sonogashira reaction was investigated between phenylacetylene and various bromoand chloroarenes containing electron neutral, electron-rich, electron-poor, electron-deficient, and sterically hindered aryl fragments. The aryl alkynes coupling products were obtained with good to excellent yields at the optimized conditions using Ni(acac)(2) (0.3 mol%)/(Ph2P)(2)py (0.6 mol%)/CuI (0.03 mol%) as the catalyst, tetrabutylammonium bromide (TBAB) as the additive, Et3N as the base in DMF at 100 degrees C under N-2 atmosphere.

Catalytic transformation of alcohols via metal-catalyzed cross-coupling reactions is very important, but it typically relies on a multistep procedure. We here report a dynamic kinetic cross-coupling approach for the direct functionalization of alcohols. The feasibility of this strategy is demonstrated by a nickel-catalyzed cross-electrophile arylation reaction of benzyl alcohols with (hetero)aryl electrophiles. The reaction proceeds with a broad substrate scope of both coupling partners. The electron-rich, electron-poor, and ortho-/meta-/para-substituted (hetero)aryl electrophiles (e.g., Ar-OTf, Ar-I, Ar-Br, and inert Ar-Cl) all coupled well. Most of the functionalities, including aldehyde, ketone, amide, ester, nitrile, sulfone, furan, thiophene, benzothiophene, pyridine, quinolone, Ar-SiMe3, Ar-Bpin, and Ar-SnBu3, were tolerated. The dynamic nature of this method enables the direct arylation of benzylic alcohol in the presence of various nucleophilic groups, including nonactivated primary/secondary/tertiary alcohols, phenols, and free indoles. It thus offers a robust alternative to existing methods for the precise construction of diarylmethanes. The synthetic utility of the method was demonstrated by a concise synthesis of biologically active molecules and by its application to peptide modification and conjugation. Preliminary mechanistic studies revealed that the reaction of in situ formed benzyl oxalates with nickel, possibly via a radical process, is an initial step in the reaction with aryl electrophiles.

A series of palladium N-heterocyclic carbenes (NHCs), complexes C1-C5, bearing dianisole backbones and substituted N-aryl moieties have been synthesized and characterized. The electronic effect as well as the steric environment of the NHC ligands has been assessed. The synthesized palladium complexes were applied for Suzuki-Miyaura cross-coupling reactions under aerobic conditions. The relationship between the catalytic structure and catalytic performance was then extensively investigated. Upon optimizing the reaction conditions, the C4 was found to be highly efficient to catalyze the cross-coupling of (hetero)aryl chlorides with (hetero)arylboronic acids at a 0.1 mol % palladium loading.

Category: chlorides-buliding-blocks. I found the field of Chemistry very interesting. Saw the article Highly Efficient Synthesis of Hindered 3-Azoindoles via Metal-Free C-H Functionalization of Indoles published in 2020, Reprint Addresses Wencel-Delord, J (corresponding author), Univ Haute Alsace, Lab Innovat Mol & Applicat, ECPM, CNRS,UMR 7042,Univ Strasbourg, 25 Rue Becquerel, F-67087 Strasbourg, France..

Although 3-azoindoles have recently emerged as an appealing family of photoswitch molecules, the synthesis of such compounds has been poorly covered in the literature. Herein a high-yielding and operationally simple protocol is reported allowing the synthesis of 3-azoindoles, featuring important steric hindrance around the azo motif. Remarkably, this C-H coupling is characterized by excellent atom economy and occurs under metal-free conditions, at room temperature, and within few minutes, delivering the expected products in excellent yields (quantitatively in most of the cases). Accordingly, a library of new molecules, with potential applications as photochromic compounds, is prepared.

The adsorption behaviors of Cu(II) and tetracycline (TC) on polyethylene microplastics that were exposed to air (A-PE-MPs), water (W-PE-MPs) and soil (S-PE-MPs) environments for a long time were investigated with batch experiments in this study. FT-IR and GC-MS analysis confirmed that phthalates (PAEs) were released from PE microplastics after exposure to UV light. When exposed to water and soil environments, PE microplastics were colonized by microorganisms and biofilms were formed on their surface. Compared with virgin microplastics (V-PE-MPs), the environment-exposed microplastics possessed higher adsorption and stabilization capacity for Cu (II) and TC. The adsorption isotherm data of V-PE-MPs and A-PE-MPs were well fitted by Freundlich model, whilst the adsorption by W-PE-MPs and S-PE-MPs were better described by Langmuir model. The Boyd equation used in kinetic experiments revealed that V-PE-MPs and A-PE-MPs were additionally affected by intra-particle diffusion compared with W-PE-MPs and S-PE-MPs. The glycosyl composition analysis suggested that the higher adsorption capacities of S-PE-MPs than W-PE-MPs could relate to the different components of extracellular polysaccharides in biofilms. Moreover, density functional theory further verified that Cu(II) and PAE adsorption on microplastics could be enhanced by the generation of Cu-PAE and Cu-PAE-TC complexes. In addition dissolved organic matter exerted opposite effects on the adsorption onto A-PE-MPs and S-PE-MPs due to their different affinity for Cu(II), TC and DOM. This study demonstrated that the contribution of microplastics to heavy metal and antibiotic migration could be affected by the way they exposed to environments.

An chelation-assisted oxidative C(sp(3))-H/N-H cross coupling of hydrocarbons with P(O)-NH compounds using copper acetate as catalyst is described. The results of kinetic experiments, mechanistic studies and DFT calculations demonstrate the importance of acetic acid coproduct as an additive for promoting the formation of intermediate bis((diphenylphosphoryl)(quinolin-8-yl)amino)copper (6), and consequently accelerating the construction of C(sp(3))-N bond. The reaction proceeded efficiently with a wide array of hydrocarbons and P(O)-NH compounds, and the rate acceleration induced by the acetic acid coproduct have been repeatedly proven. Furthermore, the efficiency of small-scale reaction could be retained upon gram-scale synthesis in a continuous manner.
