A mild and {simple|easy|straightforward|basic|uncomplicated|very simple} protocol for the synthesis of 8-azabicyclo[3.{2|two}.1]octane and 9-azabicyclo[3.{3|three}.1]nonane derivatives is described. It {provides|offers|gives|supplies|delivers} these {valuable|beneficial|useful|worthwhile|precious|important} bicyclic alkaloid skeletons in {good|great|excellent|very good|fantastic|superior} yields and {high|higher} levels of diastereoselectivity from {simple|easy|straightforward|basic|uncomplicated|very simple} and readily {available|accessible|obtainable|offered|readily available|out there} {starting|beginning} {materials|supplies|components} {using|utilizing|making use of|employing|working with|applying} visible-light photoredox catalysis.
