Preferential enrichment: a dynamic enantiomeric resolution phenomenon caused by polymorphic transitomers directly. As a reliable method to resolve a large quantity of racemic samples, however, a conventional crystallization method is still superior to the chromatographic one from the economical standpoint.

Preparative-scale separation of enantiomers on chiral stationary phases by gas chromatography,ated enantiomers are determined by chiroptics and/or by anomalous X-ray diffraction. The amounts of obtained enatiomers suffice for biological trials..Key Words: Preparative-scale GC, enantiomeric separation, chiral stationary phases, SMB-GC, nitrogen invertomer, inhalation anesthetics, terpenoids, flavours.

Book 2004enantiomer separation remains an important technique for obtaining optically active materials. Although asymmetric synthesis is a once-only procedure, an enantiomer separation process can be repeated until the optically pure sample is obtained. This book discusses several new enantiomer separation m

Retrospektive zu Michael Balints Werk, starting from an achiral reagent and in the absence of any external chiral agent has long been an intriguing challenge to chemists and is also central to the problem of the origin of optical activity on Earth.[4] In this chapter, a general method of chiral crystallization and asymmetric synthesis using the chiral crystals will be described.
