Percy Julian, Robert Robinson, and the Identity of Eserethole  Addison Ault
The Nova production Percy JulianĀForgotten Genius, which included the very public disagreement over the identity of "eserethole," the key intermediate for the synthesis of the alkaloid physostigmine, left three important chemical questions unanswered.

Sharpless Asymmetric Dihydroxylation: Effect of Alkene Structure on Rates and Selectivity  Alan C. Spivey, R. Hanson, N. Scorah, and S. J. Thorpe
Each student is assigned an alkene and performs three dihydroxylation reactions: one racemic and two enantioselective variants. The products are characterized by 1H NMR, IR, MS, [a]D20, and chiral chromatography (HPLC or GC). Comparison by the students of their results with those reported in the literature, particularly the extensive work of Sharpless, allows an exploration of the validity of Sharpless's mnemonic for predicting the stereochemical outcome of these reactions.
