Book Synopsis Organocatalytic Enantioselective Conjugate Addition Reactions by : Jose L Vicario
Download or read book Organocatalytic Enantioselective Conjugate Addition Reactions written by Jose L Vicario and published by Royal Society of Chemistry. This book was released on 2010-10-18 with total page 365 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book, unique in its field, is a comprehensive description of all the methodologies reported for carrying out conjugate addition reactions in a stereoselective way, using small chiral organic molecules as catalysts (organocatalysts). In the last 3-4 years, this has been a rapidly growing field in organic chemistry, and many papers have appeared reporting excellent protocols for carrying out these highly efficient transformations that compete well with other classical approaches using transition metal catalysts. A particularly attractive feature of this transformation relies upon the fact that the conjugate addition (Michael and Hetero-Michael reactions) is an extraordinarily effective means to initiate cascade processes which result in the formation of complex molecules from very small and simple starting blocks. The book, written by noted experts, covers all recent advances in this hot topic, and provides a good state-of-the-art review for organic chemists working in this field and all those who wish to start projects in this area.

Download or read book Catalytic Asymmetric Conjugate Reactions written by Armando Cordova and published by John Wiley & Sons. This book was released on 2010-12-01 with total page 489 pages. Available in PDF, EPUB and Kindle. Book excerpt: This unique and long-awaited handbook on this important topic in the hot field of stereoselective organic synthesis covers several types of nucleophiles. Top international authors deal with modern forms of achieving stereoselective conjugate additions based on the use of chiral auxiliaries or asymmetric catalysis, such as P-N ligands, organocatalysis, domino reactions, Lewis acid and base catalysis. There is also a discussion of the employment of enantioselective conjugate addition transformations in total synthesis of important molecules. With its reliable and previously unpublished experimental procedures, this is a true source of high quality information.

Book Synopsis Enantioselection in Asymmetric Catalysis by : Ilya D. Gridnev
Download or read book Enantioselection in Asymmetric Catalysis written by Ilya D. Gridnev and published by CRC Press. This book was released on 2016-11-03 with total page 274 pages. Available in PDF, EPUB and Kindle. Book excerpt: The field of asymmetric catalysis is currently one of the hottest areas in chemistry. This unique book focuses on the mechanism of enantioselectivity in asymmetric catalysis, rather than asymmetric catalysis from the synthetic view. It describes reliable, experimentally and computationally supported mechanisms, and discusses the danger of so-called "plausible" or "accepted" mechanisms leading to wrong conclusions. It draws parallels to enzymatic catalysis in biochemistry, and examines in detail the physico-chemical aspects of enantioselective catalysis.

Book Synopsis Catalytic Enantioselective Synthesis of Aryl Substituted 3-hydroxy-2-oxindoles and 3,3-disubstituted-2-oxindoles by : Aziza Hatice Sahin
Download or read book Catalytic Enantioselective Synthesis of Aryl Substituted 3-hydroxy-2-oxindoles and 3,3-disubstituted-2-oxindoles written by Aziza Hatice Sahin and published by . This book was released on 2010 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: In Chapter One, a catalytic enantioselective method for the synthesis of 3- hydroxy-2-oxindoles is described. 3-Hydroxy-2-oxindoles were synthesized by a nucleophilic addition of electron-rich arenes and aromatic heterocycles to substituted indole-2,3-diones (isatins) catalyzed by scandium(III) and indium(III)-inda-pybox complexes. The use of a bulky chiral ligand hindered the formation of the achiral 3,3-diaryl-2-oxindole side product. Substituted 3-hydroxy-2-oxindoles were formed in high yield and high enantioselectivity (up to 99% ee). In Chapter Two, a method for the synthesis of chiral 3,3-disubstituted-2-oxindoles from a nucleophilic substitution at the stereocenter of a substituted 3-hydroxy-2-oxindole is described. This SN̳1-like process is catalyzed by a Lewis or a Brønsted acid, which eliminates water to form an indolenium ion intermediate. Chiral BINOL-derived phosphoric acids and phosphoramides are promising catalysts for an asymmetric process, as the conjugate base can act as a counteranion that coordinates to the carbocation intermediate to direct an asymmetric nucleophilic addition. Catalyst and solvent effects have been investigated with yields ranging from 68-97%. Preliminary enantioselectivity has been observed and further optimization is underway.

Book Synopsis The Conjugate Addition of Novel Nucleophiles and Catalytic Intramolecular Tandem [1,5]-hydride Shift by : David Thompson Moon
Download or read book The Conjugate Addition of Novel Nucleophiles and Catalytic Intramolecular Tandem [1,5]-hydride Shift written by David Thompson Moon and published by . This book was released on 2008 with total page 132 pages. Available in PDF, EPUB and Kindle. Book excerpt: Investigations into the conjugate addition of phenols and sp3-hybridized carbons bound to tin, boron and silicon by transition metal catalysts through novel transmetallation pathways were undertaken with limited success. An intramolecular Lewis acid-catalyzed tandem [1,5]-hydride shift / cyclization and Friedel-Crafts acylation reaction with alkylidene Meldrum's acid derivatives has been accomplished. The use of metal phenolates as nucleophiles for transition metal catalyzed conjugate addition onto alkylidene Meldrum's acids is explored, and the ambident nucleophilic property of metal phenolates allow for the C-alkylation and O-acylation with alkylidene Meldrum's acids, producing substituted 3,4-dihydrocoumarins in modest yields. The transmetallation of rhodium complexes with alkyl boron, tin and silicon derivatives and subsequent conjugate addition onto alkylidene Meldrum's acid derivatives is investigated without success. An intramolecular Lewis acid-catalyzed [1,5]-hydride shift / cyclization reaction promoted by electron-rich aromatic rings is employed with alkylidene Meldrum's acid derivatives to furnish spiro Meldrum's acids in excellent yields. These can subsequently be used as electrophiles in the Friedel-Crafts acylation reaction, and a tandem, one-pot variation of this reaction has been accomplished in moderate to good yields. Preliminary investigations into the scope and limitations of this transformation are outlined.
