Butenolides from the Coral-Derived Fungus Aspergillius terreus SCSIO41404.

ABSTRACT: Five undescribed butenolides including two pairs of enantiomers, (+)-asperteretal G (1a), (-)-asperteretal G (1b), (+)-asperteretal H (2a), (-)-asperteretal H (2b), asperteretal I (3), and para-hydroxybenzaldehyde derivative, (S)-3-(2,3-dihydroxy-3-methylbutyl)-4-hydroxybenzaldehyde (14), were isolated together with ten previously reported butenolides 4-13, from the coral-derived fungus Aspergillus terreus SCSIO41404. Enantiomers 1a/1b and 2a/2b were successfully purified by high performance liquid chromatography (HPLC) using a chiral column, and the enantiomers 1a and 1b were new natural products.
