Abstract
An unexpected interaction with a thioglycerol matrix appeared in the liquid secondary ion mass spectrometry (LSIMS) spectra of two pyranosyl mercaptans [2,3,4,6-tetra-O-acetyl-1-thio-β-D-glucopyranose (1a) and 2,3,4,6-tetra-O-acetyl-1,5-dithio-β-D-glucopyranose (1b)] often used to prepare glucosinolates, important thiosaccharidic metabolites found in all plants of the order Brassicales. The reactions, probably occurring in the solvent cage, seem to involve radical mechanisms.
