Chirality A series of chiral and achiral objects, the interaction of polarized light with organic molecules, the assignment of R- and S- configuration, Fisher projections, and a stereospecific reaction are demonstrated.
The Synthesis of N-Benzyl-2-azanorbornene via Aqueous Hetero Diels–Alder ReactionXavier Sauvage and Lionel Delaude Characterization of the product of this organic synthesis through IR and NMR data analysis provides valuable material to familiarize students with different types of protonproton coupling patterns and their typical ranges, serves to illustrate the concepts of green chemistry and atom efficiency, and can be used to exemplify structural analysis and computational studies. Sauvage, Xavier; Delaude, Lionel. J. Chem. Educ.2008, 85, 1538.

Mosher Amides: Determining the Absolute Stereochemistry of Optically-Active AminesDamian A. Allen, Anthony E. Tomaso, Jr., Owen P. Priest, David F. Hindson, and Jamie L. Hurlburt In this experiment, teams of students are given an optically-pure amine of known structure but unknown stereochemistry. Different teams derivatize samples of the amine with (R) and (S) conformations of Mosher's acid chloride. The resulting diastereomers are analyzed by NMR to determine the absolute configuration of the initial, unknown amine. Allen, Damian A.; Tomaso, Anthony E., Jr.; Priest, Owen P.; Hindson, David F.; Hurlburt, Jamie L. J. Chem. Educ.2008, 85, 698.

Ring-Opening Polymerization of Lactide To Form a Biodegradable PolymerJennifer L. Robert and Katherine B. Aubrecht In this laboratory, students carry out the tin(II) bis(2-ethylhexanoate)/benzyl alcohol mediated ring-opening polymerization of lactide to form the biodegradable polymer polylactide. As the mechanism of the polymerization is analogous to that of a transesterification reaction, the experiment can be used to demonstrate reactions of carboxylic acid derivatives.

Mechanisms That Interchange Axial and Equatorial Atoms in Fluxional ProcessesMarion E. Cass, Henry S. Rzepa, King Kuok Hii The Berry pseudorotation is a classical mechanism for interchanging axial and equatorial ligands in molecules with trigonal bipyramidal geometry. Teaching this mechanism presents particular pedagogic problems due to both its dynamic and three dimensional character. The approach taken here illustrates these processes using interactive animations embedded in a Web page and overcomes many limitations of a printed page.

Stereochemistry TutorialNicola Burrmann Master the concepts organic stereochemistry with this interactive tutorial. It includes definitions, different three dimensional representations, assigning priorities to stereocenters, and determining the stereochemical relationship between molecules. Each section is followed by a question set that tests knowledge and understanding.

Mage; A Tool for Developing Interactive Instructional GraphicsStephen F. Pavkovic Mage is a graphics program especially well suited for visualizing three-dimensional structures of proteins and other macromolecules. It is an important tool for biochemists and finds many applications in biochemistry courses. We utilize Mage to create interactive instructional graphics of potential use in a wider range of undergraduate chemistry courses, and present some of those applications here.
