Principles of asymmetric synthesis: Introduction, Topocity in molecules Homotopic, stereoheterotopic (enantiotopic and diastereotopic) groups and facessymmetry, substitution and addition criteria. Prochirality nomenclature: Pro-R, Pro-S, Re and Si. Selectivity in synthesis:Stereo specific reactions (substrate stereoselectivity). Stereo selective reactions (product stereoselectivity): Enantioselectivity and diastereoselectivity. Conditions for stereoselectivity: Symmetry and transition state criteria, kinetic and thermodynamic control. Methods for inducing enantio and diastereoselectivity. Methodology of asymmetric synthesis: Classification of asymmetric reactions into substrate controlled, chiral auxiliary controlled, chiral reagent controlled and chiral catalyst controlled.Total Synthesis of Biological Active Compounds. |
