Preparation of beta-amino or alpha ,beta-diamino esters derived from serine

The invention relates to the prepn. of esters R1R2NCH2CH(Nu)CO2R3 (R1-R3 are protecting groups and Nu is a nucleophilic group) by reaction of R1R2NCH(CH2-Y)CO2R3 (Y is a leaving group) with a nucleophile. Thus, treatment of (R)-Bn2NCH(CH2O3SMe)CO2Me with NaN3 in MeCN afforded 90% (S)-Bn2NCH2CH(N3)CO2Me. [on SciFinder (R)]
