Abstract:
Fumiquinazoline F (1) and alantrypinone (2) have been isolated as the two major metabolites of Penicillium thymicola. The structure of 2, which contains a new ring structure, was elucidated by analysis of spectroscopic data including 2D NMR. The absolute configuration of 2 was established by a single-crystal X-ray diffraction study.
