Furan-site transformations of obacunone as potent insecticidal agents

Heliyon, 2018
Furan ring is a key pharmacophore for insecticidal activity of limoninoids. To develop natural-product-based insecticidal agents, a series of furan-site transformations (2, 3 and 3a–j) of obacunone were synthesized by selective bromination and following ...
