L-Isovaline Usage And Synthesis

Uses

a-Me-Gly(Ethyl)-OH is used in preparation of peptide compound comprising highly sterically hindered amino acid via reaction of electron-withdrawing group-protected N-unsubstituted-α,α-disubstituted amino acid with peptide followed by N-alkylation.

Purification Methods

Crystallise it from aqueous Me2CO, or better by dissolving in H2O and adding excess Me2CO. [Baker et al. J Am Chem Soc 74 4701 1952, Greenstein & Winitz The Chemistry of the Amino Acids J. Wiley, Vol 3 p 2573-2577 1961.]
