For some time now, it has been apparent to those
who teach organic chemistry that the primary audience is
not aspiring chemists, but rather pre-health students and
biology majors. However, the typical organic textbook has
not changed to reflect this reality, and the biologically
oriented material has been shoved into the last few
chapters. This material is rarely (if ever!) reached during the course of
the two semesters. As a result, most students who complete
an organic sequence have never understood the relevance of
the subject to their areas of interest. Some texts have begun
to integrate the biologically oriented topics into the text,
but Thomas N. Sorrell's Organic Chemistry has taken this
approach to new heights.
From the moment you see the cover (a stylized
rendition of the citric acid cycle), it is apparent that you are looking
at something very different in the world of organic
textbooks. Indeed, the preface details the author's desire to integrate
the reactions of metabolic and biosynthetic processes with
the typical reactions found in an organic text. If you see no
reason to change from the traditional approach to teaching
organic chemistry, then you can quit reading right now, because
this text is not for you. If, however, you agree with Sorrell
that the traditional approach does not work for students
whose interests lean toward biology, then you may want to
consider this text.
First, it must be noted that Sorrell delivers on
his promise - there is a lot of biological material in the text,
and it all shows up in the sections that cover the chemistry
of interest. As a result, in the first half of the book we see
multi-page treatments of biological SN2 reactions, the possibility
of biological E2 processes, and biological oxidation of
alcohols. Other biological topics covered early include squalene
biosynthesis, allylic oxidation, the cyclic pathway of the
arachidonic acid metabolism, and the conversion of lactate to
pyruvate (as an example of kinetic resolution). All the biological
topics fit nicely into the flow of the text.
In the book's second half, there is much more
biological material discussed. The section on Chemistry of the
Carbonyl Group contains chemistry of carbohydrates,
b-keto acid decarboxylation, biological aldol reactions,
biotin-mediated carboxylations, and fatty acid biosynthesis, among many
other biological subjects. Again, this material is incorporated
directly into the text, not included as an addendum or "special topic".
The overall result is that the organic chemistry of these
processes is apparent, and students are able to see the
obvious connection between organic chemistry and biology.
Sorrell has arranged the 26 chapters of his text into
five parts: Structural Organic Chemistry, Fundamental
Reactions of Organic Molecules, Synthetic and Spectroscopic
Methods, The Chemistry of the Carbonyl Group, and
Nitrogen-Containing Organic Molecules. Material in the first two
parts is what is typically covered in the first half of an
organic sequence and the last two parts more or less conform to
a standard second half of the course. Part III, Synthetic
and Spectroscopic Methods, deserves some mention. Along
with treatment of spectroscopic methods, Sorrell includes a
chapter on C-C bond formation (this is a wide-ranging chapter
that includes main-group and transition-metal
organometallic chemistry, retrosynthesis, and protecting groups) and
an excellent chapter on asymmetric reactions. Some may
argue that the spectroscopic material comes too late in the
course, but the chapters are self-contained, and there is no
reason that they could not be covered in a different order if desired.
My only concern with the text is the amount of
material included. At more than 1400 pages, this is a big book, and
it is easy to see why - included are many reactions that may
go beyond the scope of an introductory organic course.
For instance, in this text you will see treatments of the
Mitsunobu reaction, TMSI cleavage of ethers,
SiO2 and Al2O3
catalysis of HX addition to alkenes,
hydroxylamine-O-sulfonic acid-induced conversion of an organoborane to an amine,
vanadium-mediated epoxidation of allylic alcohols, Raney nickel
desulfurization, and the Suzuki reaction. Certainly, all
are worthwhile topics, but add significantly to the length
and scope of the book. Covering everything included would
put us back in the position of not being able to cover a
meaningful portion of the biological material because we
wouldn't get to the end of the book!
Sorrell has produced a unique organic chemistry
textbook. He has managed to integrate an enormous amount
of biological material into the text and do it in a way
that successfully shows the relationship between simple
organic reactions and complex biological processes. This
approach may well be the "new wave" in organic texts, and
Sorrell's effort deserves a serious look.
