L-Methionine related 1-amino acids by acylase cleavage of their corresponding N-acetyl-DL-derivatives
Acylase I from Aspergillus oryzae is an even more useful enzyme than suggested so far. Besides standard amino acids such as L-Met, L-Val and L-Phe, a number of additional sulfur- and selenium-containing amino acids can be obtained at useful reaction rates and in very high enantiomeric purity by kinetic resolution of the respective N-acetyl-DL-amino acids.

NEW SYNTHESES OF α-AMINO ACIDS BASED ON N-ACYLIMINO ACETATES
The reaction of N-acylamino-2-bromoacetates 2 ( via N-acylimino acetates 3 ) with higher order mixed cuprates, trimethylsilyl enol ethers and β-dicarbonyl compounds leads to a variety of α-amino acid derivatives.Their conversion into the free amino acids can be conveniently carried out by the use of t-butyl protection.In case of the N-acetyl compounds cleavage of the protecting group and optical resolution can be achieved in one step hog renal acylase.
