A chiral molecular tweezer obtained from (+)-usnic acid placed in solution in the presence of various aromatic compounds afforded complexes with low association constants. Thus, the X-ray structure of assembly 31 is presented, where the guest is sandwiched between the two pincers of the tweezer. The association constants for various guests were determined through different methods. Finally, other tweezers with electron-rich aromatic aldehydes and ketones were prepared from (1R,2R)-1,2-diaminocyclohexane. The most interesting complexes were also confirmed through structural analysis, and the best results were obtained with 10-hydroxyphenanthrene-9-carbaldehyde (51) as the aromatic moiety.

Detection of methanol in commercial biodiesel is essential to evaluate the fuel quality associated with the matter of driving safety. Compared to the standard GC method, the fluorescent detection method for methanol is much simpler and faster, but still u

A palladium-catalyzed intramolecular α-arylation and defluorinative aromatization strategy for the synthesis of polysubstituted 2-naphthols is reported. With ortho-bromobenzyl-substituted α-fluoroketones as the substrates and palladium acetate/triphenylphosphine as the catalyst, this method features good functional group tolerance, readily available catalyst and starting materials, and high yields. The applications of the strategy are demonstrated by the synthesis of useful building blocks, such as naphtha[2,3-b]furan, naphthol AS-D, and ligands/catalysts. (Figure presented.).
