Stereoselective synthesis of tetrahydroindolizines via catalytic formation of pyridinium ylides from diazo compounds

Commercially available iron (III) and copper (I) complexes catalyze new multicomponent cycloadditions between diazo compounds, pyridines and electrophilic alkenes to give alkaloid-inspired tetrahydroindolizidines in high yields and diastereoselectivities. Hitherto, catalytic formation of versatile p...

Description
Summary:Commercially available iron (III) and copper (I) complexes catalyze new multicomponent cycloadditions between diazo compounds, pyridines and electrophilic alkenes to give alkaloid-inspired tetrahydroindolizidines in high yields and diastereoselectivities. Hitherto, catalytic formation of versatile pyridinium ylides from metal carbenes has been poorly developed; the broad utility demonstrated herein sets the stage for invention of further multicomponent reactions in future.
