The synthesis of pyrrolidine and indolizidine derivatives through radical carboazidation of alkenes with α‐iodoketones, followed by reductive amination, is described. When properly substituted, further lactamization afforded pyrrolizidinones in good yield. This carboazidation/reductive amination sequence was efficiently applied to the total synthesis of three different simple alkaloids, including (±)‐monomorine
