The cis-dihydrodiol metabolite from methyl benzoate has been used as a synthetic precursor of carba-beta-L-galactopyranose, carba-beta-L-talopyranose and carba-alpha-L-talopyranose. The structures and absolute configurations of these carbasugars were determined by a combination of NMR spectroscopy, stereochemical correlation and X-ray crystallography.

Many odorants related to manufactured explosives have low volatilities and are barely detectable as odors. We previously reported that zinc metal nanoparticles increased rat olfactory epithelium responses, measured by electroolfactogram (EOG), to several odorants. Here, we report that nanomolar concentrations
