Abstract

Gandharamine (1) is a new quaternary oxobenzylisoquinolinium alkaloid found in Berberis baluchistanica Ahrendt (Berberidaceae), as well as in Thalictrum fendleri Engelm. ex Gray (Ranunculaceae). Its synthesis from dihydrobenzylisoquinoline 4 has been achieved. The only known naturally occurring close analog of gandharamine is N-methylpapaveraldine (7).
