A Simple Assignment That Enhances Students' Ability To Solve Organic Chemistry Synthesis Problems and Understand Mechanisms Jennifer Teixeira and R. W. Holman
Describes an original, easily implemented approach in which students construct a "functional group transformation" notebook which helps them to think about organic reactions in both the forward and the reverse (retrosynthetic) sense.

Synthesis of Unsymmetrical Alkynes via the Alkylation of Sodium Acetylides. An Introduction to Synthetic Design for Organic Chemistry Students Jennifer N. Shepherd and Jason R. Stenzel
Teams of students design a microscale synthesis of an unsymmetrical alkyne using commercially available terminal alkynes and alkyl halides and characterize the resulting products using TLC, IR, and 1H NMR spectroscopy. Depending on the chosen reactants, students observe both substitution and elimination products, or in some cases, no reaction at all.

Diastereoselectivity in the Reduction of α-Hydroxyketones. An Experiment for the Chemistry Major Organic Laboratory David B. Ball
Describes a research type, inquiry-based project where students synthesize racemic ahydroxyketones using umpolung, a polarity-reversal approach; investigate chelating versus non-chelating reducing agents; and determine the diastereoselectivity of these reducing processes by NMR spectroscopy.

Microscale Synthesis and Spectroscopic Analysis of Flutamide, an Antiandrogen Prostate Cancer Drug Ryan G. Stabile and Andrew P. Dicks
The synthesis involves N-acylation of a trisubstituted aromatic compound, 3-trifluoromethyl-4-nitroaniline. The procedure is easily adapted to generate structural analogues of flutamide. A significant feature is the curricular flexibility afforded by this experiment.

Organic Synthesis: The Science behind the Art (by W. A. Smit, A. F. Bochkov, and R. Caple) reviewed by Arthur R. Murdoch
In this book, the authors raise the question "Why do Organic Synthesis?" Now with the power of instrumentation at the chemist's disposal, total synthesis is no longer necessary for structure proof. So where does the future of organic synthesis lie?

Organic Chemistry (by Joseph M. Hornback) R. Daniel Libby
This text uses reaction mechanisms as the organizing principle, introduces structure where it is necessary to support the reactions to be studied, and considers synthesis after the mechanisms of appropriate reactions have been discussed.

The Art and Science of Organic and Natural Products Synthesis K. C. Nicolaou, E. J. Sorensen, and N. Winssinger
In this article, the history of the art and science of organic and natural products synthesis is briefly reviewed and the state of the art is discussed. The impact of this discipline on biology and medicine is amply demonstrated with examples, and projections for future developments in the field are made.

Grignard Synthesis of Various Tertiary Alcohols T. Stephen Everett
A general Grignard procedure is presented for the synthesis of aliphatic, tertiary alcohols containing six to nine carbons. Without revealing the specific starting materials, students are challenged to identify their unknown products from physical (boiling points, refractive indices) and spectral (infrared O-H, C-H and fingerprint regions) data.
