title: Two new compounds from the plant endophytic fungus Pestalotiopsis versicolor.
abstract: A new coumarin, 4,6-dihydroxy-7-formyl-3-methylcoumarin (1), and an α-pyrone derivative, 6-[(7S,8R)-8-propyloxiran-1-yl]-4-methoxy-pyran-2-one (2), together with four known α-pyrone derivatives (3-6), were isolated from the broth extract of the plant endophytic fungus Pestalotiopsis versicolor. Their structures were elucidated by extensive spectroscopic analysis and by comparison of the chemical shift values with those of related known compounds.
