1. Organometallic enantiomeric scaffolds: (1) the metal/ligand auxiliary attached to the unsaturated ligand influences novel reactions, controls non-traditional selectivities, and provides a dominant regio- and stereocontrol element on the scaffold that allows the predictable introduction of new stereocenters atmultiple sites around the unsaturated ligand, (2) a single metal/ligand auxiliary controls the introduction of multiple stereocenters over multiple steps, and (3) the organometallic nature of the scaffolding enables the use of stereodivergent tactics for the introduction of ring substituents.
