Lupinen‐Alkaloide, XXVI. Reaktionen mit cyclischen Enaminen

Abstract: Ausgehend von cyclischen Enaminen lassen sich stereospezifisch Hexahydrojulolidin-Derivate mit der Konfiguration des Lycopodins darstellen. Bildungsmechanismus und stereochemische Verhaltnisse werden diskutiert. Weiterhin wird eine stereospezifische Synthese des Lupinins beschrieben. Das tetracyclische Ringsystem der Lycopodium-Alkaloide enthalt ein A, B -B, C-cis&-Hexahydrojulolidin-Ringsystem, das bisher praktisch nicht synthetisch mganglich ist. Bei der katalytischen Hydrierung von Julolidin erhdt man ledig… Show more

“…There are five successful syntheses which have been done by Stork and coworkers (33), Ayer and coworkers (34), Heathcock and coworkers(35),Wenkert and Broka (36), and Schumann and coworkers(37).The unnatural 12-epilycopodine was synthesized by Wiesner and co workers(38). Several other interesting approaches were either unsuccessful or were not pursued to completion(39). The routes of those successful syntheses are strikingly different from one another.…”
