Bu3SnH mediated radical cyclizations of N-vinylic α-chloroacetamides proceeded in a ''disfavored'' 5-endo-trig manner to give five-membered lactams. Some exceptions where the 4-exo cyclization predominates are also described.

Free-radical cyclisations of a range of 2-chloro-N-(cycloalk-1-enyl)acetamides have been examined.The enamide 5, upon treatment with Bu3SnH in the presence of azoisobutyronitrile, underwent cyclisation via the carbamoylmethyl radical 6 in a 'disfavoured'
