Isoxazoline: An Emerging Scaffold in Pesticide Discovery

Isoxazolines are five-membered heterocycle compounds with a wide range of pharmacological and pesticidal activities. Numerous marketed pesticides contain an isoxazoline motif as a key skeleton. Isoxazoline compounds have relatively simple syntheses and wide biological activities against various weeds, bacteria, and other pests. In recent years, they have received increasing attention and are widely used in organic chemistry research, such as intermediate and catalyst ligands in organic synthesis. They also have excellent optoelectronic properties and are widely used in the field of materials. Hence, the exploration of isoxazoline derivatives remains an important research area in pesticide discovery. This review provides an up-to-date overview of isoxazoline heterocycle compounds utilized as pesticides and in pesticide discovery, highlighting their structure and biological properties. It summarizes relevant publications from the last 10 years, offering insights into the recent advancements in this field of research.
