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.

Formation of α-Tetralone by Intramolecular Friedel–Crafts Acylation Michael S. Holden, R. David Crouch, and Kathryn A. Barker
A microscale procedure is described for the formation of the industrially-important compound alpha-tetralone. This is an example of an intramolecular FriedelCrafts acylation, utilizing 4-phenylbutanoic acid and a proton source. The title reaction demonstrates the concept of ring-forming reactions and highlights the use of carboxylic acids as an electrophile precursor in electrophilic aromatic substitution reactions.

A Discovery-Based Friedel–Crafts Acylation Experiment: Student-Designed Experimental Procedure Anne McElwee Reeve
A discovery-based FriedelCrafts acylation experiment that includes a student-designed procedure, spectroscopic analysis of an unknown aromatic product, and molecular modeling is described. Students design the synthetic procedure and workup for the acylation of an unknown aromatic starting material in an instructor-guided classroom discussion that integrates concepts from the first semester of organic lab into a new context.

Two-Step Semi-Microscale Preparation of a Cinnamate Ester Sunscreen Analog Ryan G. Stabile and Andrew P. Dicks
The two-step synthesis and characterization of a sunscreen analog (ethyl trans-4-methoxycinnamate) is presented. This experiment is tailored towards students with a sound theoretical understanding of organic chemistry and related laboratory techniques. Appropriate synthetic discussion topics include carbonyl condensation reactions, carboxylic acid esterifications, and the so-called "cesium effect" in organic synthesis.

Synthesis of Complex Natural Products as a Vehicle for Student-Centered, Problem-Based Learning Kevin J. Cannon and Grant R. Krow
Using natural product synthesis as a vehicle, students choose a synthetic problem from the literature, identify the knowledge needed to solve the problem, explore resources for attaining that knowledge, identify the goals and criteria for a successful synthetic plan, and create and do assessments of their work.
