Two C-nucleosides bearing small fluorescent groups as a base were synthesized by Heck-type coupling reaction and incorporated into DNA. They exhibited environment-sensitive fluorescence and opposite solvatochromic properties. The modified DNAs containing 3-aminobenzonitrile or 3-aminobenzoic acid retained the duplexes and their fluorescence reflected the microenvironment.
were evaluated as catalysts for the oxidation of benzhydrol to benzophenone in the presence of Oxone® (2KHSO5·KHSO4·K2SO4) as a co-oxidant at room temperature. A study on the substituent effect of the benzene ring of N-isopropyl-2-iodobenzamide on the oxidation revealed that its reactivity increased in the following order of substitution: 5-NO2 < 5-CO2Me, 3-OMe < 5-OAc < 5-Cl < H, 4-OMe < 5-Me < 5-OMe
The present invention relates to pyridoimidazole derivatives that act as cannabinoid receptor ligands, e.g., CB2 ligands. The invention also relates to methods of preparing the compounds, compositions containing the compounds, and to methods of treatment using the compounds.

2‐arylquinazoline derivatives and tetracylic isoindolo[1,2‐a]quinazoline via cyanation followed by rearrangement of ortho‐substituted 2‐halo‐N‐arylbenzamides is described. Using dimethyl sulfoxide (DMSO) as the solvent, the cleavage of the tetracyclic isoindole fused quinazoline leads to the formation of 2‐arylquinazoline derivatives. When 1,4‐dioxane is used as the solvent, tetracyclic isoindole fused
