摘要

The structural characterization of twelve sulphur-containing alkaloids related to Thiobinupharidine and Thionuphlutine B was obtained by means of different ionization techniques and extensive metastable ion studies (Mass Analysed Ion Kinetic Energy Spectra, B/E and B2/E linked scans). Mass analysed ion kinetic energy spectroscopy of the molecular species of titled compounds allowed to differentiate syn and on ti stereochemistry of the sulphoxides.
