Abstract

Androcymbium palaestinum of Jordanian origin has yielded the new homoaporphines (+ ()-kreysigine [2) (+)-androcine [3) (+ ()-androcimine [4], (+ ()-androbine [5], (+ ()-nor-0-methylkreysigine [6], and (+ ()-norandrobine [7]. The latter two alkaloids are the first norhomoaporphines to be characterized. ()-0-Methylkreysigine [1] exists preferentially in conformation la. Hofmann degradation of (+)-androbine [5} methiodide provided androbinemethine [9], which is strongly dextrorotatory. © 1989, American Chemical Society. All rights reserved.
