A short and general synthesis of the phenanthroindolizidine alkaloids is reported, featuring an unusual amidyl radical 5-exo/5-exo/rearrangement cascade of a xanthate precursor. Second, using an amidyl radical 5-exo/6-endo cascade to synthesize a phenanthroindolizidine alkaloid exclusively has been developed through a small structural modification.
