Unusual Behaviour

Abstract The Separation of the enantiomers of D,L-allo-threoninol, necessary in racemization studies of peptide hydrolysates, gave a surprising result with respect to the elution series of the antipodes. Contrary to the rule (L before D on Chirasil-L-Val) D-allo-threoninol is eluted before its mirror image. This behaviour can only be explained by the differing importance of the asymmetric centres contained in the molecule. As a result of this and taking into account the chromatographic behaviour of allo-compounds refined model concepts of enantiomer separation must be devel-oped in future.The separation of allo-compounds of threonine, isoleucine and cystathionine is considered from this aspect.

New Stationary Phase

Chirasil-β-Dex containing an undecamethylene spacer (C11-Chirasil-Dex) was synthesized and used as chiral stationary phase (CSP) in enantioselective gas chromatography (GC). The versatility of the new stationary phase in the simultaneous enantiomeric separation of a set of N-alkylated barbiturates is demonstrated.
