Protoverbine, the parent member of a class of macrocyclic spermine alkaloids

The 17-membered macrocyclic spermine alkaloids protoverbine ((8S)-S-phenyl-1,5,9.13-tetraazacycloheptadecan-6-one. 1) and its N(9).N(13)-methylene-bridged derivative protomethine ((2S)-2-phenyl-1,5,9.14-tetraazabicyclo[12.3.1]octadecan-4-one, 2) were isol

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
