Report of iron coordinated by a bioinspired l-cystine-derived ligand catalyzed undirected arene carbon-hydrogen hydroxylation with hydrogen peroxide as the terminal oxidant to afford aryl alcs. Ar-OH [Ar = Ph, N-(phenyl)acetamide, tert-butyl(phenyl)carbamate, etc.]. The reaction was distinguished by its broad substrate scope, excellent selectivity, good yields, and it showcased compatibility with oxidation-sensitive functional groups, such as alcs., polyphenols, aldehydes and even a boronic acid. This method was well suited for the synthesis of polyphenols through multiple carbon-hydrogen hydroxylations, as well as the late-stage functionalization of natural products and drug mols.

Four categories of sulfonic acid functionalized fiber catalysts with different surface microenvironments were synthesized by covalent grafting using polyacrylonitrile fiber (PANF) as the support. After the effect of acid structure on catalytic activity was investigated by Friedlander reaction, PANEOSF was chosen for the synthesis of quinolines and coumarin derivatives with high yields and extensive substrate scope (51 examples) in ethanol or water. The effect of electrostatic microenvironment and solvent was discussed and a “release-catch-release-catch” catalytic pattern was proposed accordingly. PANEOSF can be easily recycled for 20 times without any decrease of catalytic activity. This study involved multiple reactions and reactants, such as Ethyl 4-chloro-3-oxobutanoate (cas: 638-07-3SDS of cas: 638-07-3).
