Abstract
Radical cyclisation of sp(3) carbon-centred radicals onto imines and h ydrazones provides a new method for the synthesis of 5- and 6-membered ring nitrogen heterocycles. Cyclisation onto the electrophilic carbon of the C=N group and 5-exo stereoelectronic selectivity are the domin ating mechanistic parameters. The C-centred radical intermediates were generated from benzeneselenyl precursors using Bu(3)SnH.
