A New Macrocyclic γ-Pyrone From a Southern Australian Marine Red Alga
Abstract
<jats:p>A new macrocyclic γ- pyrone (10) and two known γ- pyrones (2) and (6) have been isolated from a Victorian collection of Phacelocarpus peperocarpos. The Z geometry about ∆17,18 in (2) has been established for the first time. All structure elucidations were supported by detailed spectroscopic analysis. </jats:p>
