A new method to generate α-aminoalkyl radicals and its application to the synthesis of 6-azabicyclo[3.2.1]octanes is described. α-Amino selenoesters on heating with Bu3SnH or (Me3Si)3SiH undergo decarbonylation of the initially formed acyl radical to give the corresponding α-amino radical which could be trapped intramolecularly with a double bond bearing an electron-withdrawing group.
