Synthesis of Quaternary Ammonium Salts of Tricyclic Cationic Drugs: A One-Pot Synthesis for the Bioorganic Chemistry Laboratory  Linda S. Brunauer, Abid C. Mogannam, Won B. Hwee, and James Y. Chen
Describes a one-pot conversion of tricyclic cationic drugs to their quaternary ammonium forms for a widely used bioactive drug, chlorpromazine, a phenothiazine-based antipsychotic. The conversion of parent drug to the methylated form was evaluated by qualitatively measuring its ability to induce alterations in the shape of mammalian erythrocytes.

Synthesis and NMR Spectral Analysis of Amine Heterocycles: The Effect of Asymmetry on the 1H and 13C NMR Spectra of N,O-Acetals  Shahrokh Saba, James A. Ciaccio, Jennifer Espinal, and Courtney E. Aman
Describe an undergraduate organic laboratory experiment in which students prepare two N,O-acetals that differ only in a single ring substituent that introduces asymmetry, giving each compound a distinct 1H and 13C NMR spectral pattern that must be explained by students.

Reductive Amination: A Remarkable Experiment for the Organic Laboratory  Kim M. Touchette
The synthesis of N-(2-hydroxy-3-methoxybenzyl)-N-p-tolylacetamide is a fast, simple three-step sequence that serves as a useful example of the reductive amination reaction for the organic chemistry laboratory.

An Indexed Combinatorial Library: The Synthesis and Testing of Insect Repellents  William H. Miles, Kathy A. Gelato, Kristen M. Pompizzi, Aislinn M. Scarbinsky, Brian K. Albrecht, and Elaine R. Reynolds
An indexed combinatorial library of amides was prepared by the reaction of amines and acid chlorides; a simple test for insect repellency using fruit flies (Drosophila melanogaster) allowed the determination of the most repellent sublibraries.

A Simple Secondary Amine Synthesis: Reductive Amination Using Sodium Triacetoxyborohydride  Merle W. Carlson, James T. Ciszewski, Micah M. Bhatti, Wesley F. Swanson, and Anne M. Wilson
A reductive amination experiment for a second-semester organic chemistry class. It utilizes an imine intermediate and sodium triacetoxyborohydride, a mild reducing agent. The progress of the reaction is followed by TLC as the starting materials (the aldehyde and primary amine), the imine intermediate, and the secondary amine product are visible under ultraviolet light.
