The Same and Not the Same: Chirality, Topicity, and Memory of ChiralityWolfgang H. Kramer and Axel G. Griesbeck Describes a simple molecular approach that aids students in learning stereochemical terms, definitions, and concepts, particularly when chemical structures are drawn in two dimensions. Kramer, Wolfgang H.; Griesbeck, Axel G. J. Chem. Educ.2008, 85, 701.

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.

Synthesis and NMR Spectral Analysis of Amine Heterocycles: The Effect of Asymmetry on the 1H and 13C NMR Spectra of N,O-AcetalsShahrokh Saba, James A. Ciaccio, Jennifer Espinal, and Courtney E. Aman Describe an undergraduate organic laboratory experiment in which students prepare two N,O-acetals that differ only in a single ring substituent that introduces asymmetry, giving each compound a distinct 1H and 13C NMR spectral pattern that must be explained by students. Saba, Shahrokh; Ciaccio, James A.; Espinal, Jennifer; Aman, Courtney E. J. Chem. Educ.2007, 84, 1011.
