Phenylseleno Group Transfer in Radical Chemistry

The stereochemistry control of radical reactions has been a field of intense investigations in the last 20 years. Rules have been proposed to rationalize the results, interestingly these rules parallels the ones formerly developed for ionic and concerted reactions. The use of captodative radicals combined with phenylseleno group transfer reaction is a powerful tool which allows a wide range of chain reaction in intra and inter molecular manner. In this book we will present several aspects of these type of radical generated form selenylated alpha hydroxy acids derivatives. These reaction have been studied using different substrates. A new method of obtaining optically pure dioxalones is also presented. These reactions might be very useful during delicate steps of total synthesis of natural products. Organic chemists could find very useful some of the application that are represented in this book especially the good stereoselectivity control that these reaction have.
