Macrocyclic spermine alkaloids from Verbascum: Isolation, structure elucidation, and syntheses of the (E/Z)-isomeric pairs (S)-verbasikrine/(S)- isoverbasikrine and (S)-verbamekrine/(S)-isoverbamekrine

The isolation and structure elucidation of the 17-membered macrocyclic spermine alkaloids (S)verbasikrine (3), (S)-isoverbasikrine (6), (S)- verbamekrine (9), and (S)-isoverbamekrine (12) is presented. The syntheses of their racemates are described. The H
