Studies on the Alkaloids of Menispermaceous Plants. CXXX. Synthesis of O-Methyldauricine by Ullmann Reaction

Abstract

O-Methyldauricine (VI) was synthesized by the Ullmann reaction of l-armepavine (VIII) and l-3'-bromo-O-methylarmepavine (X). It was characterized as the dimethiodide, which was confirmed to be identical with that of natural dauricine.
