Non-Proteinogenic Amino Acid Synthesis. The β-Anion Derived from Aspartic Acid, and its Application to α-Amino Acid Synthesis.

Treatment of α-t-butyl β-methyl N-Z-(S)-aspartate (2) with lithium amide bases generates the corresponding β-ester enolate, which can be alkylated with suitable electrophiles.The application of this strategy for synthesis of optically active amino acids h

Regioselective and enantiospecific synthesis of 6-substituted and 5,6-disubstituted hexahydropyrimidines

The preference for 5- over 6-membered rings in the intramolecular cyclisation of amines with diesters can be partially overcome with mixed methyl (or benzyl), tert-butyl diesters, and this effect is enhanced where there is a β-substituent. The hexahydropy

Asymmetric Amino Acid Synthesis: Preparation of the β Anion derived from Aspartic Acid

(S)-1-t-Butyl 4-methyl N-benzyloxycarbonylaspartate (5a), and (S)-1-t-butyl 4-allyl N-benzyloxycarbonylaspartate (5b) have been synthesized from (S)-aspartic acid (2), and can be readily alkylated and hydroxyalkylated at the β-carbon for asymmetric amino acid synthesis.
