Preface

During the past two decades there has been intense interest in the development and
application of chiral chromatographic methods, particularly in the pharmaceutical
industries. This is driven both by desire to develop and exploit “good science” and
by the increasing pressure by regulatory authorities over the past ten years against
the marketing of racemic mixtures. The regulation of chiral drug provides a good
demonstration of the mutual relationship between progress in scientific methodology
and regulatory guidelines. It has also provided a common platform in establishing
good understanding between international regulatory authorities and pharamceutical
industries, leading to a consensus in recognition of the global nature of pharmaceu-
tical development. This has provided a great challenge for the industries to seek
techniques that are efficient, economical and easy to apply, in the manufacture of
enantiopure products.
The versatility of chiral stationary phases and its effecitve application in both ana-
lytical and large-scale enantioseparation has been discussed in the earlier book ‘A
Practical Approach to Chiral Separation by Liquid Chromatography’ (Ed. G. Sub-
ramanian, VCH 1994). This book aims to bring to the forefront the current develop-
ment and sucessful application chiral separation techniques, thereby providing an
insight to researchers, analytical and industrial chemists, allowing a choice of
methodology from the entire spectrum of available techniques.
I am indebted to the leading international group of contributors, who have agreed
to share their knowlegde and experience. Each chapter represents an overview of its
chosen topic. Chapter 1 provider an overview of techniques in preparative chiral sep-
aration, while Chapter 2 provides an account on method development and optimisa-
tion of enantiomer separation using macrocyclic glycopeptide chiral stationary
phase. Combinatorial approach and chirabase applications are discussed in Chapters
3 and 4. Chapter 5 details the development of membranes for chiral separation, while
Chapter 6 gives an overview of implanting techniques for enantiopurification. Non
chromatographic solid-phase purification of enantiomers is explained in Chapter
7, and Chapter 8 discusses modeling and simulation of SMB and its application in
enantioseparation. A perspective on cGMP compliance for preparative chiral chro-
matography in discussed Chapter 9, and Chapter 10 provides an account of elec-
trophoretically driven preparative chiral separation and sub- and supercritical fluid
