A series of novel spiropyrazoles and spiroisoxazolines was efficiently synthesized. Structural modifications were performed at the C-9 and C-13 positions of 9 alpha- and 9 beta-hydroxyparthenolide, which were isolated from the aerial parts of Anvillea radiata. The structures and stereochemistry of the cycloadducts were fully established by spectroscopic methods including X-ray diffraction data. (C) 2020 Elsevier Ltd. All rights reserved.
