Stereoselective synthesis of L-[15N] amino acids with glucose dehydrogenase and galactose mutarotase as NADH regenerating system
We have developed an efficient stereospecific enzymatic synthesis of L-[15N]-valine, L-[15N]-leucine, L-[15N]- norvaline, L-[15N]-norleucine and L-[15N]-isoleucine from the corresponding α-keto acids by coupling the reactions catalysed by leucine dehydrogenase and glucose dehydrogenase/galactose mutarotase. Giving high yields of L-amino acids, the procedure is economical and easy to perform and to monitor at a synthetically useful scale (1-10 g). Copyright

Stereoselective synthesis of stable isotope-labeled L-α-amino acids: Electrophilic amination of oppolzer's acyl sultams in the synthesis of L-[15N]alanine, L-[15N]valine, L-[15N]leucine, L-[15N]phenylalanine and
Using 1-chloro-1-[15N]nitrosocyclohexane, we have prepared five L-[α-15N]amino acids. The stereoselective electophillic hydroxyamination of (S)-acylbornane-10,2-sultams, followed by Zn(o)/H+ reduction, and alkaline cleavag

Chemo-Enzymatic Syntheses of Isotopically Labelled L-Amino Acids
L-Alanine labelled with carbon-13 and nitrogen-15 has been prepared in good yield and high optical purity from achiral precursors using alanine dehydrogenase.This versatile approach may be simply adapted for the preparation of a range of isotopically labe
