A benzyloxycarbonyl protected glycine equivalent 2 has been prepared in enantiopure form and has been used in the synthesis of both α-substituted amino acids and α,α-disubstituted amino acids. The process involved deprotonation to form the corresponding enolates which underwent stereoselective alkylation with various electrophiles and upon hydrolysis gave the corresponding amino acid derivatives as enantiomerically pure products.
A 2,3-butanedione protected chiral glycine equivalent--a new building block for the stereoselective synthesis of enantiopure N-protected alpha-amino acids.

A new chiral glycine equivalent 7 has been synthesised from glycidol using a chiral memory protocol, and its use in the synthesis of N-Z protected alpha-amino acids was demonstrated in a series of diasteroselective lithium enolate alkylation reactions and subsequent acid hydrolyses.
