title: Ascospiroketals A and B, unprecedented cycloethers from the marine-derived fungus Ascochyta salicorniae.
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].
