Stereochemistry is one of the most fascinating and important aspects of organic chemistry. It deals with the three-dimensional structure and spatial arrangement of molecules, which can have a profound impact on their physical, chemical and biological properties. Stereochemistry is essential for understanding the structure, function and synthesis of natural products, pharmaceuticals, polymers and materials.

One of the pioneers and leading authorities in stereochemistry was Ernest L. Eliel (1921-2008), a German-American chemist who made significant contributions to the field. He was a professor at several universities, including the University of North Carolina at Chapel Hill, where he spent most of his career. He was also a prolific author who wrote several books and articles on stereochemistry and related topics.
One of his most influential works was Stereochemistry of Organic Compounds, a comprehensive textbook that covers both the basic principles and practical aspects of stereochemistry as applied to organic compounds. The book was first published in 1994 by Wiley-Interscience, with Samuel H. Wilen and Lewis N. Mander as co-authors. The book has been widely used by students and researchers of organic chemistry as a valuable source of information and inspiration.
Stereochemistry: Definition and Concepts
Stereochemistry is the branch of chemistry that studies the spatial arrangement of atoms in molecules. It differs from constitution, which refers to the type and number of atoms in a molecule, and configuration, which refers to the connectivity or order of atoms in a molecule. Stereochemistry focuses on how atoms are oriented in space relative to each other.
Molecules that have the same constitution and configuration but differ in their spatial arrangement are called stereoisomers. Stereoisomers can have different physical, chemical and biological properties due to their different interactions with other molecules or external stimuli. For example, some stereoisomers can rotate plane-polarized light in different directions or have different smells or tastes.
The most common types of stereoisomers are enantiomers and diastereomers. Enantiomers are mirror images of each other that cannot be superimposed. They have identical physical properties except for their optical activity. Diastereomers are not mirror images of each other and can have different physical properties. A molecule that has two or more stereocenters (atoms that are bonded to four different groups) can have multiple stereoisomers.
A molecule that has a non-superimposable mirror image is called chiral. A molecule that is superimposable on its mirror image is called achiral. Chirality is a property that depends on both the molecule and its environment. A molecule that is chiral in one environment may become achiral in another environment due to symmetry or conformational changes.
A special type of achiral molecule is a meso compound, which has two or more stereocenters but has an internal plane of symmetry that makes it superimposable on its mirror image. A mixture that contains equal amounts of enantiomers is called a racemic mixture or a racemate. A racemic mixture has no net optical activity because the effects of each enantiomer cancel out.
The methods for determining and assigning absolute and relative configurations of stereoisomers include spectroscopic techniques (such as NMR, IR, UV-vis, CD), crystallographic techniques (such as X-ray diffraction), chemical methods (such as stereospecific reactions or derivatization) and computational methods (such as molecular modeling or quantum calculations).
Stereochemistry: Applications and Examples
Stereochemistry has many applications and examples in various fields of organic chemistry. Some of them are:
Physical properties: Stereoisomers can have different melting points, boiling points, solubilities, densities, refractive indices, dipole moments or specific rotations due to their different intermolecular forces or interactions with polarized light.
Chemical properties: Stereoisomers can have different reactivities, rates or mechanisms due to their different steric or electronic effects or orientations relative to other molecules or reagents.
Biological properties: Stereoisomers can have different biological activities, functions or effects due to their different interactions with enzymes, receptors or biomolecules.
Natural products: Many natural products such as amino acids, sugars, terpenes, alkaloids or steroids have complex stereochemical structures that determine their biological roles or functions.
Pharmaceuticals: Many drugs such as ibuprofen, thalidomide, penicillin or morphine have stereochemical features that affect their pharmacological actions or side effects.
Polymers: Many polymers such as polypropylene, nylon or polylactic acid have stereochemical variations that affect their physical properties such as strength, flexibility or biodegradability.
Materials: Many materials such as liquid crystals, chiral catalysts or chiral sensors have stereochemical properties that affect their optical, electrical or magnetic properties.
