摘要
Thielavic acid (1), a new isocoumarin derivative, was isolated from an endophytic fungus Thielavia sp. ECN-115, which was obtained from the stems of Crassula ovata. The relative structure of 1 was established by spectroscopic analyses including extensive 2D-NMR experiments. The absolute configuration was identified as (4S)-thielavic acid by comparing the experimental and calculated electronic circular dichroism spectra.
