The present invention relates to a process for the preparation of L-Glutamine of Formula (I). The present invention also relates to an improved process for the purification of L-Glutamine of Formula (I) having specific bulk density and Hausner ratio.
Constrained cyclic β,γ‐diamino acids were synthesized starting from l‐glutamic acid. The key steps were a Blaise reaction and a reduction that gave access to both diastereomers. Changing the protecting group can lead to either the five‐membered‐ring lactam, which can be used as a β‐amino acid, or to the six‐membered‐ring lactam, as a γ‐amino acid.
