(S)-3-amino-4-(difluoromethylenyl)cyclopent-1-ene-1-carboxylic acid (OV329, 1) is being developed for the treatment of addiction and epilepsy. The previous 14-step synthesis of OV329 was low yielding, involved an unselective α-elimination to form the cyclopentene, required the use of tert-butyllithium, and produced toxic selenium by-products in the penultimate step. A new synthesis, which avoids the aforementioned issues, was carried out on large scale, reducing the step count from 14 to 9 steps and increasing the overall yield from 3.7% to 8.1%.
