Regiospecific complexation of the dimethoxy arene ring of (–)-canadine to chromiumtricarbonyl, protection of the C-11 position, followed by stereoselectivesubstitution at C-8 effects, after deprotection and decomplexation, a stereoselectivesynthesis of (–)-(8R)-methylcanadine; a comparison is made with a racemic sample synthesised by an alternative route.
