The Synthesis of a Cockroach Pheromone Patty L. Feist
This paper describes the synthesis of gentisyl quinone isovalerate or blattellaquinone, a sex pheromone of the German cockroach and a compound with real-world applications. The experiment also affords students practice in extraction as well as IR and NMR spectroscopy.

Grubbs's Cross Metathesis of Eugenol with cis-2-Butene-1,4-diol To Make a Natural Product. An Organometallic Experiment for the Undergraduate Lab Douglass F. Taber and Kevin J. Frankowski
Describes the ruthenium catalyzed cross metathesis of eugenol with cis-1,4-butenediol. The experiment is an excellent example of the powerful selectivity possible with the Grubbs' catalyst, demonstrating the preference for trans over cis alkene formation and for cross metathesis over homodimerization.

Monoterpene Unknowns Identified Using IR, 1H-NMR, 13C-NMR, DEPT, COSY, and HETCOR Lisa T. Alty
This set of NMR experiments can be a capstone experience for a spectroscopy or advanced laboratory course following organic chemistry. Students are given a monoterpene to identify using IR, 1H-NMR, 13C-NMR, and DEPT data. Once the unknown is identified, they can fully interpret and assign each carbon and each proton signal to the structure using COSY and HETCOR along with the one-dimensional NMR data. The rigidity of the ring systems and the chiral centers in all of the compounds present diastereotopic hydrogens and, in some cases, diastereotopic methyl groups.
