Resolution and regioselective protection of glutamic acid analogues. I- Resolution of diastereomeric α-boroxazolidone derivatives
Diastereomeric α-boroxazolidone γ-phenylethylamide (or γ-phenylethanolamide) derivatives of 2-, 3- or 4-substituted glutamic acid analogues have been separated by silicagel chromatography, resulting, after deprotection, in a practical method for the resolution of most of these unnatural amino acids.

Synthesis and resolution of DHCGA, a new conformationally rigid 3,4-dehydroglutamic acid analogue
(±)-1-amino-2-cyclohexene-1,3-dicarboxylic acid (DHCGA),an unsaturated cyclic analogue of glutamic acid, was prepared from 3-carboxy-4-cyclohexenone by a Bucherer-Bergs reaction. Resolution was performed through coupling with L-leucine and separation of the resulting diastereoisomeric dipeptides. Spectral data, including optical rotation and circular dichroism of both enantiomers of DHCGA are reported.

CHEMOENZYMATIC SYNTHESIS OF CONFORMATIONALLY RIGID GLUTAMIC ACID ANALOGUES
All stereomers of cyclohexane cyclopentane-derived analogues of glutamic acid have been synthesized from the corresponding 3-keto-cycloalkyl carboxylic acid esters by a combination of microbial steps and standard chemical methods.
