Asymmetric conjugate addition-cyclization of lithium amide of 6-membered hydrazine 4, piperidazine, (or 5-membered hydrazine 6, pyrazolidine) to N-(E)-cinnamoyl-(1S)-2,10-camphorsultam (1S)-3 afforded β-amino acid derivative (S)-1 {or (S)-2} for the synthesis of polyamine alkaloids in good yield with good stereoselectivity (up to 86% ee).
