Stereoselectivity in organic chemistry is the preference of a reaction to produce one stereoisomer over another. It's essential for drug development, as biological systems often favor one enantiomer, affecting drug effectiveness and side effects. Key reactions like Aldol, Epoxidation, and Diels-Alder illustrate the importance of controlling stereochemistry in synthesis, impacting pharmaceuticals and materials science.
