Notes: Isolation of the New (- )-(3 R,4S)-4-Hydroxymellein from the Fungus Septoria nodorum Berk

Abstract

The new (-)-(3 R,4 S)-4-hydroxymellein (6) is isolated from the fungus Septoria (Phaeosphaeria) nodorum Berk, together with the previously reported isomer 5. The results so far obtained in this series of metabolites are discussed in relationship with biosynthetic considerations.
