A convenient approach to N-Boc amino ketones 3a~3l has been developed, which features a SmI2 prompted one-pot radical addition-ring opening process of 2-piperidinone with α,β-unsaturated esters. Moreover, the indolizidine skeleton (6) has been successfully synthesized from the key methyl (S)-8-((tert-butoxycarbonyl)amino)-5-((tert-butyl- dimethylsilyl)oxy)-4-oxooctanoate (3e), which undergoes one-pot deprotection-condensation-reduction-amination process.

Key words: samarium diiodide, 2-piperidinone, radical addition-ring opening, indolizidine
