An efficient procedure was developed for the asymmetric synthesis of (S)-diethyl (2-(1,3-dioxoisoindolin-2-yl)propyl)phosphonates employing (S)-diethyl (1-diazo-2-(1,3-dioxoisoindolin-2-yl)alkyl)phosphonates as starting materials. The reaction was catalyzed by 5% Pd/C and used glacial acetic acid as additive in i-PrOH as solvent. The obtained optical β-amino phosphonate derivatives were identified by 1H NMR, 13C NMR, 31P NMR and HRMS and the enantiomeric excess was 95%. This process provided straightforward access to optical β-aminophosphonate derivatives in good yields with high stereoselectivities.

Key words: chiral induction, β-amino phosphonate, asymmetric synthesis, α-diazophosphonate
