description

Festuclavin (1), 6-Cyano-6-nor-1 (3), 6-Nor-1 (5) und 6-Allyl-6-nor-1 (7) lassen sich in flussigem Ammoniak mit Kalium und dem entsprechenden Iodid in ihre 1-Allyl- und 1-Propyl-Derivate uberfuhren. Die Darstellung von 7 aus 5 wird beschrieben. Partial Syntheses of New Ergoline Derivatives from Clavine Alkaloids, V: Festuclavines Mono- and Disubstituted at N-1 and N-6 Festuclavine (1), 6-cyano-6-nor-1 (3), 6-nor-1 (5) and 6-allyl-6-nor-1 (7) were converted to their 1-allyl- and 1-propyl derivatives with potassium and the corresponding iodide in ammonia. The preparation of 7 from 5 is described.
