title: Lysergylpeptides in the course of peptide ergot alkaloid formation.
abstract: Radioactive d-lysergyl-Val-Leu-OMe, d-lysergyl-Val-Val-OMe and d-lysergyl-Val-Val-Pro-OMe were synthetized according to the dicyclohexylcarbodiimide/1-hydroxybenzotriazole procedure. These compounds are not used by intact mycelium of Claviceps as immediate precursors for cyclolalkaloid biosynthesis.
