Three new hydroxylated lactones piliferolide A, B, and C (3-5), derived from oleic and palmitic acid have been isolated from liquid cultures of Ophiostoma piliferum, a fungus associated with aspen. Their structures, including absolute configuration, have been determined from spectroscopic data and by chemical studies.
