Freshman Organic Chemistry (CHEM 125)
Professor Barry Sharpless of Scripps describes the Nobel prize-winning development of titanium-based catalysts for stereoselective oxidation, the mechanism of their reactions, and their use in preparing esomeprazole. Conformational energy of cyclic alkanes illustrates the use of molecular mechanics.
