Chen, Weiqiang published the artcileSwitchable and efficient conversion of 2-amido-aryl oxazolines to quinazolin-4(3H)-ones and N-(2-chloroethyl)benzamides, COA of Formula: C7H6N2, the main research area is amidophenyloxazoline chemoselective reaction; chloroethylbenzamide preparation; quinazolinone preparation.

Switchable chemoselective conversion of 2-amido-aryl oxazolines to quinazolin-4(3H)-ones or N-(2-chloroethyl)benzamides was achieved. The former reaction was proposed to involve a PIFA-mediated 6π electrocyclization followed by an in situ nucleophilic substitution, while the latter reaction uses aluminum chloride as a halogenated source through a ring-opening reaction. The reactions proceed smoothly under mild conditions and have excellent functional group compatibility.

Zhao, Yanbin published the artcileVanadium-catalyzed Oxidative Conversion of Primary Aromatic Alcohols into Amides and Nitriles with Molecular Oxygen, Quality Control of 100-70-9, the main research area is amide preparation green chem; nitrile preparation green chem; aldehyde preparation green chem; acid preparation green chem; primary alc ammoxidation vanadium catalyst; Alcohol; Amide; Catalytic oxidation; Nitrile; Vanadium.

Herein, a vanadium-based material V-N-C-700 was prepared via a simple and convenient method, and employed for liquid-phase catalytic ammoxidation of alcs. RCH2OH (R = n-Bu, Ph, pyridin-2-yl, etc.) with mol. oxygen. By using V-N-C-700/2-picolinic acid, primary aromatic alcs. were smoothly converted into the amides RC(O)NH2 and nitriles RCN in the presence of urea. The corresponding aldehydes RCHO are the key intermediates, and 2-picolinic acid could significantly enhance oxidation of alcs. into aldehydes. The amides were formed simultaneously along with nitriles, rather than only from nitriles via successive hydration. This work further expands non-noble metal catalysts for the preparation of amides and nitriles.

Aliphatic, aromatic, and heteroaromatic aldehydes were readily converted to corresponding nitriles in a one-pot reaction sequence with hydroxylamine and sulfuryl fluoride. The reaction proceeds at room temperature, does not require metal catalysts and special precautions, and produces nitriles in excellent yields. It is compatible with a variety of functional groups, can be performed in aqueous and organic solvents, and is readily scalable to multigram quantities. Mild conditions and high selectivity of the reaction enabled the construction of polyfunctional probes containing nitrile, alkyne, azide, and fluorosulfate groups for further orthogonal derivatization.
