Solid-phase synthesis of anandamide analogues.

The endocannabinoids are amides and esters of arachidonic acid that can mimic the pharmacological properties of Delta(9)-tetrahydrocannabinol (Delta(9)-THC). Anandamide, the most prominent of the endocannabinoids, has been implicated in both metabolic/physiological roles of the central nervous system, making it an attractive medicinal target. As such, we report the first solid-phase methodology that expedites access to various anandamide analogues. Our synthesis features a repetitive Cu-mediated coupling reaction between terminal alkynes and propargyl halides or allylic halides.
