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 centurya 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 DielsAlder 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.
