Stereospecific Synthesis of the Geometrical Isomers of a Natural Product T. Grove, D. DiLella, and E. Volker
Presents an experiment for the synthesis of (Z) and (E) isomers that is presented to students as a puzzle in which they must determine the identity of the major component in anise oil. A necessary part of the analysis is the preparation the (E) and (Z) isomers of anethole. Molecular modeling is used to explore the conformation of and energy difference between isomers.

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.

Synthesis of Derivatives of (1R)-(-)- and (1S)-(+)-10-Camphorsulfonic Acid Steven C. Cermak and David F. Wiemer
The preparation of optically active (camphorsulfonyl)oxaziridines from commercially available (1R)-(-) and/or (1S)-(+)10-camphorsulfonic acid provides a clear demonstration of the lack of relationship between absolute configuration and optical rotation. The parent sulfonic acid can be converted to the corresponding acid chloride and then to the sulfonamide, sulfonylimine, and finally to an oxaziridine in a series of practical organic laboratory experiments.
