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Alder 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.

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.

Organic Spectroscopy Laboratory: Utilizing IR and NMR in the Identification of an Unknown Substance  Neil M. Glagovich and Timothy D. Shine
An undergraduate organic laboratory designed to teach the use of IR and NMR spectra interpretation in the identification of an unknown substance has been developed. This laboratory requires the student to obtain the IR spectrum of an unknown substance and, from the interpretation of that spectrum, determine which of several possible functional groups is present in the molecule. Using this information and either the melting point or boiling point of the unknown, the student is able to determine a list of likely candidates (usually between eight and twelve suspects collated from a supplied table of possible compounds). The student will then draw the structures for all candidate compounds and, from those structures, predict the 1H- and 13C-NMR spectra for each.

Generation, Isolation, and Characterization of a Stable Enol from Grignard Addition to a Bis-Ester. A Microscale Experiment for the Undergraduate Organic Chemistry Laboratory  Olivier J.-C. Nicaise, Kyle F. Ostrom, and Brent J. Dalke
A microscale experiment for the undergraduate organic chemistry laboratory that consists of preparing and characterizing an alpha-ketoester and its corresponding, remarkably stable enol form, has been developed. The reaction is that of a Grignard reagent with a bis-ester. A difference in reaction temperature is responsible for the selective generation of the alpha-ketoester and the enol ester. Analysis of spectral data (1H NMR and IR) and a knowledge of organic reactions allows the students to determine the detailed structure of the two reaction products and also to suggest a mechanism for their formation. This experiment introduces students to the concept of stability of the tetrahedral intermediate in acyl-transfer reactions. It also gives them a taste of the unexpected.

The Ethylene Ketal Protecting Group Revisited: The Synthesis of 4-Hydroxy-4,4-diphenyl-2-butanone  Marsha R. Baar, Charles E. Russell, and Kristin L. Wustholz
The multistep synthesis of 4-hydroxy-4,4-diphenyl-2-butanone from ethyl acetoacetate illustrates the use of a ketal protecting group. Reaction of ethyl acetoacetate with ethylene glycol with p-TsOH in toluene produced the ketal ester. Reaction of the crude ketal ester with two equivalents of phenyl magnesium bromide followed by an aqueous acid workup generated the tertiary alcohol and simultaneously removed the ketal protecting group to produce the hydroxyketone. Our procedure is a modification of a previously published synthesis whose end product was 4,4-diphenyl-3-buten-2-one, the dehydrated analog.

A six-period laboratory exercise has been developed that uses the convenient Sharpless asymmetric dihydroxylation (AD) to illustrate the principles of a chiral synthesis. Using one particular alkene, students perform a racemic dihydroxylation, an AD using a commercially available AD-mix, and then an AD using an ester derivative of dihydroquinidine that they synthesized themselves. The structures of the products are confirmed with 1H NMR spectroscopy and the enantiomeric excesses of the diols are determined using a chiral GC column.

Application of the Correlation Method to Vibrational Spectra of C60 and Other Fullerenes: Predicting the Number of IR- and Raman-Active Bands  Kazuo Nakamoto and Michael A. McKinney
The C60 molecule (Buckyball/soccer ball) exhibits only 4 IR and 10 Raman bands although it possesses 174 (3 x 60 - 6) normal vibrations. This striking reduction in the number of observed bands is evidently due to the molecule's extremely high symmetry (Ih point group).
