Yuremamine is a phytoindole alkaloid which was isolated from the bark of Mimosa tenuiflora in 2005, and erroneously assigned a pyrrolo[1,2-a]indole structure that was thought to represent a new class of indole alkaloids.[1] However in 2015, the bioinspired total synthesis of yuremamine revealed its true structure as a flavonoid derivative.[2] It was also noted in the original isolation of yuremamine that the alkaloid occurs naturally as a purple solid, however through total synthesis it was revealed that yuremamine as a free base is colorless, and the formation of a trifluoroacetate salt during HPLC purification led to the purple color.[2]
