Eudistomin U and Isoeudistomin U, New Alkaloids from the Carribean Ascidian Lissoclinum fragile

Abstract

Chemical investigations of the Caribbean ascidian Lissoclinum fragile (Didemnidae) have resulted in the isolation of new alkaloids which we have designated eudistomin U [1] and isoeudistomin U [2]. Their structures were determined by spectrometric and chemical means.
