Pericyclic Reactions: Theory and Mechanism

Pericyclic reactions are crucial for complex organic synthesis, but understanding their concerted, symmetry-controlled mechanisms can be challenging. This course demystifies the theory behind these fascinating transformations. By focusing on orbital symmetry, you will gain the ability to accurately predict the feasibility, stereochemistry, and pathway of a wide range of thermal and photochemical pericyclic reactions, making complex synthesis predictable. What you'll learn: * Understand the fundamental concept of concerted reactions and the major types: cycloadditions, electrocyclic, and sigmatropic shifts. * Learn how to apply Frontier Molecular Orbital (FMO) theory, identifying HOMO and LUMO interactions in reacting species. * Master the Woodward-Hoffmann rules for predicting the stereochemical outcome of thermal and photochemical pericyclic processes. * Apply these theoretical concepts to analyze and predict the stereoselectivity of common cycloaddition reactions, including the Diels-Alder reaction. * Practice determining the conrotatory and disrotatory ring opening and closing modes in electrocyclic reactions. The course begins by establishing the core principles of molecular orbitals and symmetry, then systematically introduces the rules governing each major reaction class, followed by practical examples. This course is designed for students and professionals new to advanced organic chemistry mechanisms, requiring no prior knowledge of orbital symmetry beyond basic molecular structure.
