Moreover,a series of sensitive substituents such as nitro, ester, cyano and vinyl groups were tolerated under present conditions. It was confirmed that OH units in the ligand were crucial for the catalytic activity. Notably, this research exhibited the potential of metal-ligand bifunctional ruthenium catalysts for the hydrogen auto-transfer process.

Ma, Wei published the artcileIron-Catalyzed Anti-Markovnikov Hydroamination and Hydroamidation of Allylic Alcohols, COA of Formula: C8H11NO, the main research area is allylic alc iron catalyst anti Markovnikov hydroamination hydroamidation.

Hydroamination allows for the direct access to synthetically important amines. Controlling the selectivity of the reaction with efficient, widely applicable, and economic catalysts remains challenging, however. This paper reports an iron-catalyzed formal anti-Markovnikov hydroamination and hydroamidation of allylic alcs., which yields γ-amino and γ-amido alcs., resp. Homoallylic alc. is also feasible. The catalytic system, consisting of a pincer Fe-PNP complex (1-4 mol %), a weak base, and a nonpolar solvent, features exclusive anti-Markovnikov selectivity, broad substrate scope (>70 examples), and good functional group tolerance. The reaction could be performed at gram scale and applied to the synthesis of drug mols. and heterocyclic compounds When chiral substrates are used, the stereochem. and enantiomeric excess are retained. Further application of the chem. is seen in the functionalization of amino acids, natural products, and existing drugs. Mechanistic studies suggest that the reaction proceeds via two cooperating catalytic cycles, with the iron complex catalyzing a dehydrogenation/hydrogenation process while the amine substrate acts as an organocatalyst for the Michael addition step.

Lambright, Alison L. published the artcileMechanism-Based Design of an Amide-Directed Ni-Catalyzed Arylboration of Cyclopentene Derivatives, Formula: C8H11NO, the main research area is borylated cyclopentane amide derivative preparation; crystal structure borylated cyclopentane amide derivative; mol structure borylated cyclopentane amide derivative; amide directed nickel catalyzed diastereoselective arylboration cyclopentene derivative.

A method for amide-directed Ni-catalyzed diastereoselective arylboration of cyclopentenes is disclosed. The reaction allows for the synthesis of sterically congested cyclopentane scaffolds that contain an easily derivatized boronic ester and amide functional handles. The nature of the amide directing group and its influence on the reaction outcome were studied and ultimately reflect a predictably selective reaction based on the solvent and base counterion.

Zhou, Cong published the artcilePhotoredox-Catalyzed α-Aminomethyl Carboxylation of Styrenes with Sodium Glycinates: Synthesis of γ-Amino Acids and γ-Lactams, Safety of 4-Methoxy-N-methylaniline, the main research area is arylaminoarylbutanoic acid arylbutyrolactam regioselective preparation; ruthenium photoredox catalyst regioselective aminomethylcarboxylation arylaminoglycine aryl alkene; iridium photoredox catalyst regioselective aminomethylcarboxylation lactamization arylaminoglycine aryl alkene.

A visible-light photoredox-catalyzed reductive α-aminomethyl carboxylation of styrenes and 1,1-diarylalkenes with sodium N-arylglycinates and CO2 has been developed to synthesize a series of α,α-disubstituted γ-amino acids such as MePhNCH2CH2CPh2CO2H and γ-lactams such as 1,3,3-triphenyl-2-pyrrolidinone with high efficiency and regioselectivity. Notably, CO2 released from the decarboxylation step can be reused for the subsequent carboxylation. Distinct from the previous reactions with the same type of substrates leading to simple decarboxylation and olefin hydroalkylation, this process involves addnl. CO2 sequestration, thus leading to olefin α-aminomethyl carboxylation. These findings not only provide new access to α,α-disubstituted γ-amino acids and γ-lactams but also serve as a proof of concept for CO2 reutilization in decarboxylation reactions.
