A continuous mesofluidic process has been developed for benzylic C-H oxidation with moderate to good yields using a photocatalyst (riboflavin tetraacetate, RFT) activated by a UV lamp and an iron additive [Fe(ClO4)2] via incorporation of singlet oxygen (1O2) for the direct formation of oxidized C=O or CH-OH compounds.

A mild and practical tandem oxidative ring-opening/cyclization reaction mediated by Ce4+ for the synthesis of 1-tetralones is presented. This rapid transformation was completed within 30 s and conducted in an open reactor at 0 °C in a water-acetonitrile mixture. Various cyclobutanol derivatives are transformed into desired products in good to high yields, and this reaction can be easily scaled up to the gram scale.

Simple dissolution of an arylalkyl acid chloride in 1,1,1,3,3,3-hexafluoro-2-propanol promotes an intramolecular Friedel-Crafts acylation without additional catalysts or reagents. This reaction is operationally trivial in both execution and product isolation (only requiring concentration followed by purification) and accommodates a broad range of substrates. Preliminary studies that bear upon potential reaction mechanisms are reported.

supporting information, p. 7924 - 7927 (2015/07/27)
A regioselective synthesis of 1-tetralones via silver-catalyzed ring expansion is described. A variety of 1-tetralones are furnished under mild reaction conditions from tertiary cyclobutanols regardless of the electronic properties and steric hindrance of substituents, providing a new and practical method to access diverse 1-tetralone building blocks. Preliminary experimental and DFT studies revealed that a radical-mediated sequence of C-C bond cleavage/C-C bond formation is involved.

4,5,6,7-Tetrahydro-benzothiophen-7-ylamines, 4,5,6,7-tetrahydro- benzothiophen-4-ylamines, and 5,6-dihydro-4H-thieno[2,3-b] thiopyran-4- ylamines were designed, synthesized, and tested as OH radical scavengers. Most of them displayed chemical scavenging properties better than or in the same range as salicylic acid. Moreover, some compounds were able to protect in vitro the astroglial glutamate transporters against inhibitory action of radicals promoted by xanthine/xanthine oxidase. Thus, such compounds might be useful for lowering the large amounts of excitotoxic glutamate liberated during acute CNS diseases: they might protect the glutamate reuptake in astrocytes from the inhibitory action due to radicals co-liberated with glutamate.
