  • The role of cationic intermediates in the benzylidene-directed synthesis of 1,2-cis glycosidic linkages is unclear. Now cryogenic infrared spectroscopy provides insight into the SN1 mechanism of benzylidene-directed glycosylation reactions. The analysis reveals that cationic intermediates form anhydro cations through a two-step process, which correlates with the observed stereochemical outcome.

  • Glycolipids are glycoconjugates with important biological functions, but techniques for their analysis are deficient. Here, the authors report the use of cryogenic gas-phase infrared spectroscopy to investigate isomerism in a set of immunologically relevant glycolipids, and show that their structural features can be accurately resolved based on a narrow spectral fingerprint region.
