4'-Fluorocannabidiol

4'-Fluorocannabidiol (also known as PECS-101 and 4'-F-CBD, and formerly as HUF-101 and HU-474[1]) is a fluorinated cannabidiol derivative that has more potent anxiolytic, antidepressant, antipsychotic and anti-compulsive activity in mice compared to its parent compound.[2][3][4][5] It was first synthesized in 2016, alongside 10-fluorocannabidiol diacetate and 8,9-dihydro-7-fluorocannabidiol, which showed much weaker activity.[2]

Synthesis

4'-Fluorocannabidiol has been synthesized from isolated cannabidiol by putting it in dry dichloromethane and adding 1-fluoropyridinium triflate.[2]
