Strategies for the synthesis of canonical, non-canonical and analogues of strigolactones, and evaluation of their parasitic weed germination activity

Abstract Strigolactones (SLs) are natural products with promising applications as agrochemicals to prevent infestation parasitic weeds due their ability trigger seed germination. However, use is still limited because of the low yields in which they isolated from sources. As such, numerous studies have led strategies for obtaining them, and various structural analogues, by organic synthesis. These analogues focused attention on study SLs, some them easier synthesize possess enhanced properties, such level bioactivity. This review provides an overview synthesis subsequently focusing production canonical structure. The germinating activity compounds also described herein, positive effects different species problematic genera Striga , Orobanche Phelipanche having been found. highly active analogue GR24 currently most widely studied literature, relevant structural-activity relationships proposed a result derivatives functionalized positions. Analogues based other SLs strigol orobanchol developed, novel derived eudesmanolide or guaianolide sesquiterpene lactones. aims provide useful information development bioactive applicable new generation herbicides, attempt employ similar those produced naturally ecosystems that provoke effective herbicide at concentrations.
