Eliel's textbook "Stereochemistry of Carbon Compounds" (1962) and another text that he co-authored, "Conformational Analysis" (1965) profoundly influenced several generations of organic chemists. The monumental latest version "Stereochemistry of Organic Compounds", co-authored with S. H. Wilen (1994), with its 1267 pages, may well be the last single-volume compendium on this subject. Eliel's research also focused on stereochemistry, particularly on the conformational analysis of mobile systems, cyclohexanes and saturated heterocycles. Using NMR extensively, he probed the idea that the most reactive conformation of a flexible molecule might not be its most stable conformation.
An excellent teacher, Eliel's honors include the MCA College Chemistry Teacher's Award (1965) and the George C. Pimentel Award in Chemical Education (1995). Eliel held many positions in the American Chemical Society, including Chairman of the Board of Directors (1987-9) and President (1992). In 1996 he received the top ACS award, the Priestley Medal.
When the Nazis came to power, he left Germany and moved to Scotland, then Canada, then Cuba. He received his B.S. from the University of Havana in 1946.[1] He moved to the United States in 1946 and taught at the University of Notre Dame from 1948. In 1972 he moved to be the W.R. Kenan, Jr. Professor of Chemistry at the University of North Carolina at Chapel Hill until his retirement in 1993. Eliel was elected a Fellow of the American Academy of Arts and Sciences in 1980.[3] In 1981, Eliel became a founding member of the World Cultural Council.[4] He served as president of the American Chemical Society in 1992. In 1995 he received the George C. Pimentel Award in Chemical Education, and in 1996 he was awarded the Priestley Medal of the American Chemical Society. He died in Chapel Hill, North Carolina.[2]
His research focussed on the stereochemistry and conformational analysis of flexible organic molecules, including derivatives of cyclohexane and saturated heterocyclic rings, using nuclear magnetic resonance spectroscopy (NMR) extensively. His 1962 textbook Stereochemistry of Carbon Compounds influenced generations of organic chemists.[1] The most recent edition is Stereochemistry of Organic Compounds, co-authored in 1994 with Samuel H. Wilen.[1][5]
Stereoisomers are compounds with the same chemical formula and the same connectivity, but different arrangements in three-dimensional space. The study of stereoisomers and their chemical effects is known as stereochemistry. Despite having identical chemical formulae, stereoisomers can have drastically different biological properties.
A Practical Introduction to Stereochemistry
Stereoisomers are compounds with the same chemical formula and connectivity but with different arrangements of their atoms in 3-dimensional space. Stereochemistry encompasses the study of stereoisomers and their properties. Despite having an identical chemical formula, stereoisomers can have drastically different biological, medicinal, and chemical properties. Basic Organic Stereochemistry explains in clear, concise terms the concepts and properties of stereoisomers.
Ideal both as a text for advanced undergraduate or graduate students and as a handy guide for researchers in industry, this superb text covers:
* Polarimetry and optical rotation
* Internal coordinates, configuration, and conformation
* Nature of stereoisomers
* Barriers between stereoisomers and residual stereoisomers
* Symmetry operators and symmetry point groups
* Properties of stereoisomers and stereoisomer discrimination
* Separation of stereoisomers, resolution, and racemization
Suitable for students in organic and biological chemistry, Basic Organic Stereochemistry is unparalleled as a convenient text.

The teaching activity will be carried out through lectures with the aid of slides. Selected papers from the literature will be discussed and some exercises will be performed during the lessons
The slides used during the lessons are available to students on the Elly platform and will be loaded on a monthlyweekly basis. The subscription to the online course is required to download the files containing the slides. In addition, references of original papers are furnished to permit a deeper study.
There will be spaces for interaction with students
The oral exam will take place face to face or remotely if the health emergency continues.
At the end of the course the student is expected to be able to:
The assessment of learning will take place through an oral examination. The oral examination consists of a discussion of the topics dealt with during the course.
In particular, the acquisition of a correct stereochemical language will be verified, as well as the understanding the reaction mechanisms leading to stereoselective and enantioselective processes. Knowledge of concerted reactions and of various approaches to functionalise solid (nano) materials will be checked. Green chemistry approaches to synthesis will be discussed.
The oral test is evaluated on a scale of 0-30. The oral test shall be communicated immediately upon completion of the test.
Please note that online registration on the application is compulsory.
Stereochemistry is about the shape and change of shape of molecules.There are several textbooks on this topic. This recent book has auniquefeature: Several months after its publication (It was published inOctober1998), the author has already established a website [1] for this bookat enhanced diagrams, answers to problems and an updatedbibliographyare provided and are freely accessible.
This book can be used as reading material for students takingorganicchemistry courses and for graduate students. Organic chemists like mecanalso brush up their knowledge on stereochemistry, particularly organicstereochemistry. The copy I received is a paper-back version. The sizeand the volume of this book also make reading it comfortable. At theendof each chapter, references for further reading are provided, includinga reference to the appropriate chapter of the definativestereochemistrytext Stereochemistry of Organic Compounds by Eliel and Wilen[2]
I am always interested in how the authors of stereochemistry booksusestereochemical representations, because the solid wedge, broken wedge,broken line, solid bar, and broken bar are all frequently used forstructuraldrawing. A large number of combinations of these representations havebeenseen in literature, which have caused confusion and ambiguity [3]. Inthistext, stereochemical representation is introduced in Chapter 1. Thefirstfigure defines correct (black and gray) and incorrect (red or blue)representationsof a tetrahedron (also at the ).
Figure 1.4 of the book, which is reproduced here as Figure 2, is arepresentativeand nice illustration of the graphics contained in this book.Unfortunatelythe print version has graphics in black and white. Therefore, you maywishto visit this book's website [1], enjoying its colourful figures and 3Dmolecular structures and further enhanced graphics.
