Zhao, Guangkuan published the artcileA Broad Substrate Scope of Aza-Friedel-Crafts Alkylation for the Synthesis of Quaternary α-Amino Esters, Synthetic Route of 151-10-0, the main research area is chloroaminal arene Friedel Crafts alkylation amino ester regioselective preparation.

A versatile synthetic protocol of aza-Friedel-Crafts alkylation has been developed for the synthesis of quaternary α-amino esters. This operationally simple alkylation proceeds under ambient conditions with high efficiency, regioselectivity, and an exceptionally broad scope of arene nucleophiles. A key feature of this alkylation is the role associated with the silver(I) salt counteranions liberated during the reaction. Taking advantage of a phase-transfer counteranion/Bronsted acid pair mechanism, we also report a catalytic enantioselective example of the reaction.

China, Hideyasu published the artcileRegiodivergent oxidation of alkoxyarenes by hypervalent iodine/oxone system, Application In Synthesis of 151-10-0, the main research area is monomethoxyarene iodobenzoic acid oxone regioselective oxidation green chem.

The combination of Oxone with an organoiodine compound, i.e., 2-iodobenzoic acid (2-IB), selectively yields p-quinones from monomethoxyarenes under mild conditions was reported. In this reaction system, an organoiodine compound was immediately oxidized by Oxone to generate cyclic hypervalent iodine (III) species in-situ, which served as the specific mediator for the selective p-quinone synthesis, preventing o-quinone formation.

He, Xinxin published the artcileBis-selenonium Cations as Bidentate Chalcogen Bond Donors in Catalysis, SDS of cas: 151-10-0, the main research area is bis selenium cation catalyst preparation Lewis acid; imine diene selenium catalyst aza Diels Alder reaction; dienophile diene selenium catalyst Diels Alder reaction; arene selenium catalyst bromination.

Hydrolytically stable bidentate Lewis acid catalysts derived from selenonium dicationic centers were developed. The bis-selenonium catalysts were employed in the activation of imine and carbonyl groups in various transformations with good yields and selectivity. Lewis acidity of the bis-selenonium salts was found to be stronger than that of the monoselenonium systems, attributed to the synergistic effect of the two cationic selenonium centers. In addition, the bis-selenonium catalysts were not inhibited by strong bases or moisture.

The asym. aminomethylation reaction of 3-diazooxindoles with electronic-rich arenes and N,O-acetals cooperatively catalyzed by achiral dirhodium complex and chiral phosphoric acid is reported. The reaction provides a novel method for the facile synthesis of chiral 3-aminomethyl oxindoles with an all-carbon quaternary center in good yields (82-98%) with high to excellent enantioselectivities (up to 97% ee). The transformation proceeds through a convergent addition of a reactive zwitterionic intermediate with a chiral methylene iminium generated in situ via asym. counteranion-directed catalysis (ACDC). This work represents the first asym. aminomethylation method of mixed 3,3′-bisindoles with structural diversity.

A palladium-catalyzed protocol for synthesizing diaryl sulfones RS(O)2R1 (R = Ph, 1-naphthyl, 2-thienyl, etc.; R1 = Ph, 2,4,6-trimethylphenyl, 2-naphthyl, etc.) from the arenes R1H through C-H activation is described.
