Both processes most likely proceed via hydrometallation of the alkene as outlined in Scheme 10.1. The intermediate metalalkyl (I) can then undergo overall formylation or silylation

The focus in this chapter will be mainly on the use of non-racemic. additives, e.g. ligands and/or catalysts, in asymmetric conjugate additions. The chapter begins with a brief introduction to the chemistry of conjugate additions. After this it is organized

Based on recent results, it seems likely that future advances in the asymmetric version of the palladiumcatalysed allylic substitution reaction will be made through an u

This is because the titanium/tartrate catalyst system proved to be the first simple method to induce asymmetry that approached the goal of universal applicability and predictability. Already in this book, several examples of t
