Fructosylation of ergot alkaloids by submerged cultures of Claviceps purpurea inhibited in alkaloid production
Lysergol β-O-D-fructoside and 9,10-dihydrolysergol β-O-D-fructoside were prepared from their respective aglycones by transfructosylation using submerged cultures of Claviceps purpurea inhibited in ergot alkaloid production by 5-fluorotryptophan.The same culture also oxidizes lysergol to penniclavine.
