The Chromium(VI) Oxide Oxidation of Epimeric 1,2,3,4-Tetrahydro-1-naphthols

Crystal structure of rac-2,3-diphenyl-2,3,5,6-tetrahydro-4H-1,3-thiazin-4-one 1-oxide

In the title compound, C16H15NO2S [alternative name: rac-2,3-diphenyl-1,3-thia-zinan-4-one 1-oxide], the thia-zine ring exhibits an envelope conformation, with the S atom forming the flap. The sulfoxide O atom is in a pseudo-axial position on the thia-zine ring and is trans to the phenyl group on C-2. The phenyl rings form a dihedral angle of 89.47 (19)°. In this racemate crystal, homochiral mo...

Nitidine chloride (NC), a quaternary ammonium alkaloid, has numerous pharmacological effects, such as anticancer activity. However, it was found that NC also has hepatocellular toxicity. Because organic cation transporters 1 and 3 (OCT1 and OCT3) might mediate the influx of NC into hepatocytes, multidrug and toxin extrusion 1 (MATE1) probably mediates the efflux of NC from hepatocytes, while cy...

On the oxidation of D-1, 3-thiazane-4-carboxylic acid (D-tetrahydro-1,3-thiazine-4-carboxylic acid).

Catalytic Oxidation of 4-Methylpyridine on Modified Vanadium Oxide Catalysts

The reaction of gas-phase oxidation of 4-methylpyridine on individual V2O5, binary and ternary vanadium-oxide catalysts was studied. These catalysts were modified by additives of SnO2 and TiO2. It was found that modifying V2O5 leads to increase the activity of binary contacts. Upon transition from binary V2O5<...
