Ascospiroketals A and B, Unprecedented Cycloethers from the Marine-Derived Fungus <i>Ascochyta </i><i>salicorniae</i>

Abstract

Chemical investigation of the marine-derived fungus Ascochyta salicorniae led to the isolation of two novel natural products, ascospiroketals A (1) and B (2). From a biosynthetic standpoint, the compounds possess new ring systems. [structure: see text].
