Book Description
Allylic boron compounds have gained a prominent position as a truly practical class of synthetic reagents in the past twenty-five years. Their main application as a method for the stereoselective synthesis of homoallylic alcohols by allyl-transfer to carbonyl compounds is essentially unmatched. In this process, a new carbon-carbon bond is formed, and up to two new stereogenic centers are created in a predictably controlled manner. Highly effective and general enantioselective variants are available, with countless applications in the total syntheses of polyacetate and polypropionate natural products. Furthermore, the residual allylic unit can be manipulated through a number of different transformations such as oxidative cleavage, olefin metathesis, hydrometalations, and many others. The discovery of Lewis and Brønsted acid catalyzed manifolds recently, has opened new doors for further development of this important reaction. This book provides an up-to-date, comprehensive survey of the literature of this rich chemistry as it pertains to organic synthesis. Consistent with the goal of Organic Reactions, the content and presentation emphasize the preparative aspects of the reactions, giving considerable attention to the scope and limitations of the individual transformations along with detailed experimental procedures. A tabular survey of all examples of carbonyl allylboration used in organic synthesis is presented in nine tables organized by type of allylic boron reagent with listings within each table according to increasing carbon number of the carbonyl substrates. The literature is covered through December 2010, including a new listing of nearly 200 literature citations that supplement the original coverage of 834 references used in the earlier hard cover version of the chapter. Allylboration of Carbonyl Compounds is intended to be a useful, easily read reference book for all practitioners of synthetic organic chemistry working in academic and industrial laboratories.

Book Description
This series provides the most comprehensive and highly focused treatment of important organic reactions currently available. All volumes of Organic Reactions (including this one) are collections of chapters each devoted to a single reaction or a definitive phase of a reaction, of wide applicability. The authors have had experience with the processes surveyed. The subjects are presented from the preparative viewpoint and particular attention is given to limitations, interfering influences, effects of structure and the selection of experimental techniques. Each chapter includes several detailed procedures illustrating the significant modifications of the method.

Book Description
Volume 88 represents the tenth single-chapter-volume produced in our 73-year history. Such single-chapter volumes represent definitive treatises on extremely important chemical transformations. The success of the research efforts over the past 20 years forms the basis for the single chapter in this volume namely, Hydroamination of Alkenes by Alexander L. Reznichenko and Kai C. Hultzsch. The authors have compiled an enormous (and growing) literature and distilled it into an extraordinarily useful treatise on all aspects of the hydroamination process.

Book Description
The two chapters in Volume 83 describe reactions that represent two major (and growing) franchises in the Organic Reactions series, namely, transition metal catalyzed cross-coupling reactions and multicomponent reactions. These two processes not only have a rich history in synthetic organic chemistry, but also represent some of the most commonly employed transformations in the modern practice of molecule construction. The first chapter authored by Eiichi Nakamura, Takuji Hatakeyama, Shingo Ito, Kentaro Ishizuka, Laurean Ilies, and Masaharu Nakamura describes one of the most exiting advances in the field of transition metal catalyzed cross-coupling reactions: the use of iron catalysts. The second chapter authored by Stephen G. Pyne and Minyan Tang describes the latest in a long line of multicomponent reactions published in this series: the boronic acid Mannich reaction, sometimes called the Petasis reaction.
