The regioselectivity of intramolecular addition of sp(3) carbon-centred radicals onto C=N double bonds of imines and hydrazones is influenced by the position and polarisation of the C=N bond.

Radical cyclisation of sp3 carbon-centred radicals onto imines and hydrazones 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 dominating mechanistic parameters. The C-centred radical intermediates were generated from benzeneselenyl precursors using Bu3SnH
