Synopsis C-H Activation for Asymmetric Synthesis by : Françoise Colobert

Provides, in one handbook, comprehensive coverage of one of the hottest topics in stereoselective chemistry Written by leading international authors in the field, this book introduces readers to C-H activation in asymmetric synthesis along with all of its facets. It presents stereoselective C-H functionalization with a broad coverage, from outer-sphere to inner-sphere C-H bond activation, and from the control of olefin geometry to the induction of point, planar and axial chirality. Moreover, methods wherein asymmetry is introduced either during the C-H activation or in a different elementary step are discussed. Presented in two parts?asymmetric activation of C(sp3)-H bonds and stereoselective synthesis implying activation of C(sp2)-H bonds?CH-Activation for Asymmetric Synthesis showcases the diversity of stereogenic elements, which can now be constructed by C-H activation methods. Chapters in Part 1 cover: C(sp3)-H bond insertion by metal carbenoids and nitrenoids; stereoselective C-C bond and C-N bond forming reactions through C(sp3)?H bond insertion of metal nitrenoids; enantioselective intra- and intermolecular couplings; and more. Part 2 looks at: C-H activation involved in stereodiscriminant step; planar chirality; diastereoselective formation of alkenes through C(sp2)?H bond activation; amongst other methods. -Covers one of the most rapidly developing fields in organic synthesis and catalysis -Clearly structured in two parts (activation of sp3- and activation of sp2-H bonds) -Edited by two leading experts in C-H activation in asymmetric synthesis CH-Activation for Asymmetric Synthesis will be of high interest to chemists in academia, as well as those in the pharmaceutical and agrochemical industry.

Synopsis Enantioselective CpRu-catalyzed Decarboxylative C-C Bond Forming Reactions by : David Linder

La combinaison du précatalyseur stable à l'air [CpRu([eta]6-C10H8)] [PF6] avec des ligands de type pyridine-monooxazoline a permis de développer une nouvelle stratégie pour effectuer des réactions de substitution allyliques avec des conditions expérimentales simples. Cette famille de ligands est apparue particulièrement appropriée pour effectuer l'étude de réactions du type réarrangement de Carroll. Le mécanisme de cette réaction a été étudié et un cycle catalytique raisonnable en a découlé. Une stratégie de double activation par co-catalyse a donc été développée: l'utilisation synergique de sels de magnésium a permis d'effectuer ces réactions à température ambiante et donc de manière plus sélective.

Synopsis P-stereogenic Ligands in Enantioselective Catalysis by : Arnald Grabulosa

P-stereogenic ligands were among the first to be used in asymmetric catalysis but synthetic difficulties and prejudices have hampered their development. However, continuous screening for new chiral ligands means that they can no longer be ignored and this rigorous reference source reflects their renaissance.The book is filled with many examples from recent primary literature. The synthetic chemist will easily be able to follow the preparation methods which are accompanied by a description of the challenges and limitations. Those working in homogenous catalysis, and wanting to increase their repertoire of ligands, will be able to establish which have already been used in each reaction and their performance.This book provides comprehensive coverage of the application of P-stereogenic ligands in homogeneous catalysis. It begins with a brief chapter on generalities of P-stereogenic compounds: history, configurational stability, and interconversions among them.The book then goes on to describe the main preparative methods, from resolution of racemates to enantioselective catalysis, before focusing on the catalytic applications of P-stereogenic ligands. Chapter 7 describes the use of the ligands in catalytic hydrogenation and related reactions whereas chapter 8 deals with other reactions, mainly C-C bond forming reactions. The aim of these two final chapters is to give an outline of the usefulness of the ligands in homogeneous catalysis.
