Abstract
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.
