Pseudoephedrine-Directed Asymmetric α-Arylation of α-Amino Acid Derivatives
Available α-amino acids undergo arylation at their α position in an enantioselective manner on treatment with base of N′-aryl urea derivatives ligated to pseudoephedrine as a chiral auxiliary. In situ silylation and enolization induces diastereoselective migration of the N′-aryl group to the α position of the amino acid, followed by ring closure to a hydantoin with concomitant explulsion of the recyclable auxiliary. The hydrolysis of the hydantoin products provides derivatives of quaternary amino acids. The arylation avoids the use of heavy-metal additives, and is successful with a range of amino acids and with aryl rings of varying electronic character.

Chromatographic Resolutions of Racemates, XI. Comparison of Optically Active Polyamides and Cellulose Triacetate
On optically active polyacrylic and polymethacrylic amides (1a-e) as well as on microcrystalline cellulose triacetate (2), numerous racemates including drugs are separated at least partially, the amide 4f completely on cellulose triacetate.By repeated chromatography on the polyamide 1a, (+)- and (-)-mandelic acid (4a) and (+)-hexobarbital (9d) also were obtained optically pure.

Racemic and Optically Active Hydantoins from Disubstituted Cyanoacetic Acids
Starting from the chiral disubstituted cyanoacetic acids 1 the racemates and some enantiomers of the 5,5-disubstituted hydantoins 6 and of the 3-methylhydantoins 7 are synthesized via the isocyanates 3.Their absolute configurations are determined.
