Frank Westheimer's Early Demonstration of Enzymatic Specificity  Addison Ault
Reviews one of the most significant accomplishments of one of the most respected chemists of the 20th century┬Ła series of stereospecific enzymatic oxidation and reduction experiments that led chemists to recognize enantiotopic and diastereotopic relationships of atoms, or groups of atoms, within molecules.

A Simple Method for Drawing Chiral Mononuclear Octahedral Metal Complexes  Aminou Mohamadou and Arnaud Haudrechy
This article presents a simple and progressive method to draw all of the octahedral complexes of coordination units with at least two different monodentate ligands and show their chiral properties.

A Green Enantioselective Aldol Condensation for the Undergraduate Organic Laboratory  George D. Bennett
The proline-catalyzed aldol condensation between acetone and isobutyraldehyde proceeds in good yield and with high enantioselectivity at room temperature. This multi-week experiment also illustrates a number of principles and trade-offs of green chemistry.

Diels–Alder Synthesis of endo-cis-N-Phenylbicyclo[2.2.2]oct-5-en-2,3-dicarboximide  Marsha R. Baar and Kristin Wustholz
endo-cis-N-Phenylbicyclo[2.2.2]oct-5-en-2,3-dicarboximide was synthesized by a Diels┬ŁAlder cycloaddition of 1,3-cyclohexadiene and N-phenylmaleimide in ethyl acetate. 1,3-Cyclohexadiene and N-phenylmaleimide were selected to illustrate the Alder rule, which reflects a preference for endo products and to overcome the difficulties associated with the traditional combination of 1,3-cyclopentadiene and maleic anhydride.
