- A METHOD OF PRODUCTION OF 2,4-DIHYDROXYBUTYRIC ACID
-
A method for the preparation of 2,4-dihydroxybutyric acid (2,4-DHB) including the successive steps of converting malate, succinyl-CoA and/or glyoxylate into malyl-CoA, converting malyl-CoA previously obtained into malate-4-semialdehyde, and converting malate-4-semialdehyde into 2,4-DHB using a DHB dehydrogenase.

- A new efficient synthesis of nicotianamine and 2′-deoxymugineic acid
-
Nicotianamine and 2′-deoxymugineic acid, phytosiderophores, have been efficiently synthesized, which will be suitable for large scale production of these plant physiologically important compounds. The synthetic method for 2′,3″-dideoxy-3″-oxomugineic acid was also investigated.

- Synthesis and Nuclear Magnetic Resonance Studies of Some N-Acylated Methyl 4-Amino-4,6-dideoxy-α-D-mannopyranosides
-
The methyl α-glycosides of 4-amino-4,6-dideoxy-D-mannopyranose (perosamine), N-acylated with either formic, acetic, or (S)-2,4-dihydroxybutanoic acid, have been synthesized.The (1)H and (13)C n.m.r. spectra of these substances and the parent, non-N-acylated glycoside, demonstrated how the chemical shifts are influenced by the N-acylation.The N-formyl derivative occured in two conformations, s-cis and s-trans, and the free-energy barrier between these, 86.9 kJ mol-1, was defined by dynamic n.m.r. spectroscopy.
