Enantiomer Separation: Fundamentals and Practical Methods
This is a modern and "green" procedure of enantiomer separation. These separation methods are described in several chapters of the book. Biological separation methods and "green" methods are covered in two chapters.

One enantiomer of a chiral drug is usually more active than the other in fighting a
disease. In 1992, the U.S. Food and Drug Administration (FDA) released long-
awaited guidelines for the marketing of chiral drugs. The decision about whether
to ...

Invitation to Organic Chemistry
Fortunately, the inactive R enantiomer is not harmful to the body. Why is one
enantiomer physiologically active while the other is not? For a molecule to have a
biological effect, it must interact with a particular receptor site in the body.

For an equimolar mixture of two enantiomers, the rotation induced by one
enantiomer exactly cancels that of the other, and the mixture does not rotate the
plane of polarized light. Such a 50 : 50 mixture of enantiomers is optically inactive
and is ...

□FIGURE | 10.7 Mirror Stereoisomers and biochemistry (a) The enantiomers of
carvone and the aminoacid asparagine have very different flavors. (b) One
stereoisomer ofa drug may have a very different biological effect than its
enantiomer.

C02H ,C02H Ph C02H (6) (7) r-Bu CO2H OH (8) As mentioned above, one of the
limitations of using naturally occurring resolving agents is that only one
enantiomer of the compound being resolved may be readily accessible by
resolution.

Organic Chemistry: An Intermediate Text
If one enantiomer is present in excess over the other, then the solution will have a
net rotation corresponding in sign (+ or −) to that of the more abundant
enantiomer. The composition of the mixture is denoted by the optical purity or the
percent ...
