Mass spectrometry, especially tandem mass spectrometry, has been widely used in the field of analytical sciences for handling biological and chemical samples. The technique resolves molecular and fragment ions based on the mass to charge ratio. Energy-resolved mass spectrometry (ERMS) further provides an activation energy-related factor in the dissociation reaction. Therefore, it is a very powerful...
Various C-glycosyl indoles and pyrroles were synthesized within a few minutes through coupling acetobromo sugars with suitably substituted indoles and pyrrole in the presence of catalytic amounts of InCl 3 at room temperature. Most of the glycosylations proceeded with a high stereoselectivity.
