Two2-oxyphenanthridinium alkaloids have been isolated from EgyptianPancratiummaritimum and identified as ungeremine and zefbetaine using spectroscopic and chemical methods. The identification of zefbetaine was supported by its partial synthesis from pseudolycorine and by comparison with its unnatural isomer, iso-zefbetaine, which was in turn prepared from sternbergine.

Abstract
Two2-oxyphenanthridinium alkaloids have been isolated from EgyptianPancratiummaritimum and identified as ungeremine and zefbetaine using spectroscopic and chemical methods. The identification of zefbetaine was supported by its partial synthesis from pseudolycorine and by comparison with its unnatural isomer, iso-zefbetaine, which was in turn prepared from sternbergine.File in questo prodotto:
