摘要：

Three new gamma-butenolides, aspertamarinolides A-C, were isolated from the marine-derived fungus Aspergillus tamarii PSU-MF90. Their structures with absolute configurations were elucidated by spectroscopic techniques, electronic circular dichroism (ECD) calculations and specific rotations. A plausible biosynthetic pathway for the isolated gamma-butenolides was also proposed. (C) 2020 Elsevier Ltd. All rights reserved.
