Rocaglamide is a natural product which belongs to a class of molecules called flavaglines.[1][2] This compound was isolated in 1982 by Ming-Lu King (金明儒) and colleagues based on its antileukemic activity.[3] The name of Rocaglamide is named from two parts: Roc- and aglamide. Roc- means Republic of China (中華民國), where this product was first isolated; aglamide indicates this product is isolated from Large-leaved Aglaia (Scientific name: Aglaia rimosa[4]). Like other flavaglines, rocaglamide displays potent insecticidal, antifungal, anti-inflammatory and anticancer activities. Rocaglamide A (RocA) inhibits eukaryotic translation initiation by binding to the translation initiation factor eIF4A and converting it into a translational repressor.[5]

Rocaglamide was first synthesized by Barry Trost in 1990.[6] Although other syntheses have been described since, Trost’s remains the only one to afford rocaglamide in an enantio-specific manner.
