Book Description
L'ADDITION RADICALAIRE D'ALDEHYDES SUR DES ALCENES FONCTIONNALISES OU NON AVEC AMORCAGE PAR LES PEROXYDES CONDUIT A LA FORMATION DE DEUX ADDUITS CETONIQUE ET ALDEHYDIQUE. ON MET EN EVIDENCE L'IMPORTANCE RELATIVE DES TROIS ETAPES (AMORCAGE, ADDITION, TRANSFERT), CONFIRMEE PAR L'UTILISATION DE NOUVEAUX PEROXYDES, D'OU L'OBTENTION DU SEUL ADDUIT CETONIQUE ET DU SEUL ADDUIT ALDEHYDIQUE. LES EFFETS STERIQUES SE SONT REVELES DETERMINANTS LORS DE L'ETAPE D'ADDITION, TANDIS QUE LES EFFETS POLAIRES GOUVERNENT ESSENTIELLEMENT L'ETAPE DE TRANSFERT D'HYDROGENE SUR LES DEUX SITES DE L'ALDEHYDE. LA SYNTHESE D'ACETATES, DE BETA -CETOLS PAR VOIE RADICALAIRE A PERMIS D'OBTENIR PLUSIEURS ENONES ISOMERIQUEMENT PURES

Book Description
Most syntheses in the chemical research laboratory fail and usually require several attempts before proceeding satisfactorily. Failed syntheses are not only discouraging and frustrating, but also cost a lot of time and money. Many failures may, however, be avoided by understanding the structure-reactivity relationship of organic compounds. This textbook highlights the competing processes and limitations of the most important reactions used in organic synthesis. By allowing chemists to quickly recognize potential problems this book will help to improve their efficiency and success-rate. A must for every graduate student but also for every chemist in industry and academia. Contents: 1 Organic Synthesis: General Remarks 2 Stereoelectronic Effects and Reactivity 3 The Stability of Organic Compounds 4 Aliphatic Nucleophilic Substitutions: Problematic Electrophiles 5 The Alkylation of Carbanions 6 The Alkylation of Heteroatoms 7 The Acylation of Heteroatoms 8 Palladium-Catalyzed C-C Bond Formation 9 Cyclizations 10 Monofunctionalization of Symmetric Difunctional Substrates

Book Description
Classics in Total Synthesis II is the long awaited sequel to Classics in Total Synthesis, a book that has made its mark as a superb tool for educating students and practitioners alike in the art of organic synthesis since its introduction in 1996. In this highly welcomed second volume, K.C. Nicolaou and Scott A. Snyder discuss in detail the most impressive accomplishments in natural product total synthesis during the 1990s and the first years of the 21st century. While all of the features that made the first volume of Classics so popular and unique as a teaching tool have been maintained, in this new treatise the authors seek to present the latest techniques and advance in organic synthesis as they beautifully describe the works of some of the most renowned synthetic organic chemists of our time. Key features include: Systematically develops domino reactions, cascade sequences, biomimetic strategies, and asymmetric catalysis through the chosen synthesis Discusses cutting edge synthetic technologies in terms of mechanism and scope Presents new reactions, such as olefin metathesis, in mini-review style Includes abundant references for further reading CD with useful teaching material for lecturers is included with hardback version (ISBN 3-527-30685-4) Graduate students, educators, and researchers in the fields of synthetic and medicinal chemistry will wish to have a copy of this book in their collection as an indispensable companion that both augments and supplements the original Classics in Total Synthesis. From the reviews: "... a volume, (...) which any chemist with an interest in synthetic organic chemistry will wish to acquire." –JACS (on the previous volume) "...this superb book (...) will be an essential purchase for many organic chemists." –Nature (on the previous volume) "...Classics II is undoubtedly an excellent bargain that is highly recommended to everybody interested in advanced organic chemistry. One of my co-workers confessed that Classics I was the book on his bedside table while he prepared his thesis defense. Isn't that the highest distinction for a monograph? I have every reason to believe that Classics II will equally stand the selection process by students (and probably their supervisors too)." –Angewandte Chemie, 2004 "Well, there is a new pleasant read for the advanced student and even the experienced. It is the second volume to the established Classics in Total Synthesis and it continues the series extremely well." –ChemBioChem, 2004 "...the real innovation of this volume is the inclusion of alternative pathways to the same target molecule by other researchers. This enables the reader to appreciate that there are also other solutions to certain structural problems than those of the original synthesis. ... Let us hope that K. C. Nicolaou and his associates will present us with these future achievements in the same clear, informative and innovative format they have with the previous two volumes." –Applied Organometallic Chemistry
