Diastereoselectivity in the Reduction of α-Hydroxyketones. An Experiment for the Chemistry Major Organic Laboratory David B. Ball
Describes a research type, inquiry-based project where students synthesize racemic ahydroxyketones using umpolung, a polarity-reversal approach; investigate chelating versus non-chelating reducing agents; and determine the diastereoselectivity of these reducing processes by NMR spectroscopy.

Keynotes in Organic Chemistry (Andrew F. Parsons) Joel M. Karty
As a result of the trend towards modularization of chemistry courses, the text attempts to meet the need for smaller, highly focused and accessible organic chemistry textbooks, which complement the very detailed standard texts, to guide students through the key principles of the subject.

Diastereoselective Synthesis of (+/-)-1,2-Diphenyl-1,2-propanediol. A Discovery-Based Grignard Reaction Suitable for a Large Organic Lab Course James A. Ciaccio, Roxana P. Bravo, Antoinette L. Drahus, John B. Biggins, Rosalyn V. Concepcion, and David Cabrera
An experiment that probes the diastereoselectivity of the reaction between a Grignard reagent and a common, inexpensive alpha-chiral ketone; introduces students to pi-facial discrimination by having them establish the stereochemical course of kinetically controlled nucleophilic addition to a carbonyl.

A crossed aldol condensation for the undergraduate laboratory Angres, Isaac; Zieger, Herman E.
This two-step experiment for undergraduate organic chemistry students illustrates three basic ideas: organic chemistry students illustrate three basic ideas (1) crossed aldol condensation; (2) the acidity of benzylic hydrogen in hydrocarbons; and (3) reduction of a double bond in hydride transfer.
