WebRetrosynthetic analysis is a technique for solving problems in the planning of organic syntheses. This is achieved by transforming a target molecule into simpler precursor structures regardless of any potential reactivity/interaction with reagents. Each precursor material is examined using the same method. WebJul 30, 2024 · Formalized and popularized as a problem-solving strategy by the American Nobel prize-winning chemist E. J. Corey in the late 1960s, retrosynthesis involves the application of chemical reaction rules to deconstruct target structures into precursors, and then assessing the availability and suitability of potential reactants.
