Synthesis of 5(10→9)abeo-ergolines

Mantegani, Sergio,Arlandini, Emanuele,Borghi, Daniela,Brambilla, Enzo,Varasi, Mario

, p. 1493 - 1506 (2007/10/03)

Reaction of the (5 R, 8 R)-ergoline derivative (6) with the couple CCl4/(Ph)3P unexpectedly resulted in the formation of the novel (5 S, 8 R)-5 (10→9)abeo-ergoline derivative. A mechanism of this transposition process is proposed.
