The ring expansion of hydroxycyclopropanes can be exploited for the formation of heterocycles. Progress towards the synthesis of homochiral nitrogenous heterocycles, including pyrrolidines, piperidines, and azepines via cationic and radical ring fragmentation/recondensation strategies will be presented.
