Stereoselective syntheses of alpha, beta-diamino acids
(1984)
A method for the threo-stereoselective synthesis of (alpha),(beta)-diamino acids has been developed. This method was applied to the synthesis of (5-chloro-2-piperidinyl)glycine (streptolutine) and analogs of streptolutine. ...
Asymmetric synthesis of [alpha]-amino acids and [alpha]-amino aldehydes via electrophilic substitution of chiral lithiocarbanions
(1982)
The asymmetric syntheses of N-protected-(alpha)-amino acid derivatives are reported. Deprotonation of N-benzoylglycine (-)-menthol ester (1) with lithium diisopropylamide (LDA) affords the stable dilithio derivative (9). ...
