Lissoclinolide, the first non-nitrogenous metabolite from a Lissoclinum tunicate

The isolation and characterization of a new metabolite from the tunicate Lissoclinum patella is described. The structure of lissoclinolide [1] was solved using spectral and chemical methods, and it is shown to be the first non-nitrogenous, non-sulfur-containing compound to be isolated from the genus Lissoclinum.
