Fast-Atom-Bombardment Mass-Spectrometry In The Stereochemical Characterization Of A New Group Of C30 Nuphar Alkaloids
RAPID COMMUNICATIONS IN MASS SPECTROMETRY(1993)
摘要
A new group of thio-C30 nuphar alkaloids has been obtained from the three main stereoisomers by complete oxidation of the sulphur and both the tertiary nitrogen sites. High-resolution mass spectrometry and metastable-ion decomposition analysis were used to distinguish and characterize diastereoisomers.
