Asymmetric Synthesis via Heterocyclic Intermediates; XXX¹. Asymmetric Synthesis of Glutamic Acids and Derivatives thereof by the Bislactim-Ether Method. Michael-Addition of Methyl 2-Alkenoates to the Lithiated Bislactim-Ether of Cyclo-(L-Val- Gly)

All articles of this category An asymmetric synthesis of (virtually configurationally pure) ( R )-glutamic acids and/or the corresponding ( R )-2-amino-5-pyrrolidinones starting with the bis-lactim ether of cyclo-(L-Val-Gly) and methyl 2-alkenoates is described.
