title: Role of the delta 8 double bond of agroclavine in lysergic acid amide biosynthesis by Claviceps purpurea.
abstract: Agroclavine, given to actively-growing sclerotial tissue of a strain of Claviceps purpurea which can not normally elaborate ergot alkaloids, was transformed by this tissue into lysergic acid amide with overall efficiency of approximately 40%. By contrast, festuclavine (8,9-dihydro-agroclavine) was not transformed, indicating specificity in the mechanism of lysergyl biosynthesis.
