This work describes an efficient synthesis of enantiomerically pure (R)-2-aminomethylalanine, (R)-2-aminomethylnorvaline, (R)-2-aminomethylvaline, (R)-2-aminomethylleucine and (R)-2-aminomethylphenylalanine by electrophilic amination of chiral 2-cyanoeste

A strategy of highly selective alkylation of chiral 2-cyanoesters followed by the corresponding degradation process allows a divergent asymmetric synthesis of (R) and (S)-α-methylphenylalanine.
Asymmetric Synthesis of β-Lactams. Highly Diastereoselective Alkylation of Chiral 2-Cyano Esters

Enolates derived from 10-(dicyclohexylsulfamoyl)isobornyl 2-substituted-2-cyanoacetates were alkylated with very good yield and high diastereoselectivity.The reduction of the resulting reaction products and subsequent cyclization of the β-amino acids led
