This book was released on 2003 with total page 367 pages. Available in PDF, EPUB and Kindle. Book excerpt: Iminoacetonitriles have been shown to function as aza dienophiles in intramolecular Diels-Alder reactions, affording substituted quinolizidines and indolizidines. The cycloadducts are formed with a high preference for an exo-orientated cyano group due to the a-amino nitrile anomeric effect. The substrates for these [4+2] cycloadditions are prepared from readily available alcohols via a Mitsunobu reaction with the previously unknown N-cyanomethyltriflamide (HN(Tf)CH2CN) followed by cesium carbonate promoted elimination of trifluoromethanesulfinate. The a-amino nitrile cycloadducts are versatile synthetic intermediates and can be elaborated via alkylation, reduction, and nucleophilic addition chemistry to provide a variety of substituted and functionalized nitrogen heterocycles. Initial investigations have been undertaken to explore the use of this methodology in the total synthesis of alkaloid natural products.

Available in PDF, EPUB and Kindle. Book excerpt: Iminoacetonitriles participate as activated imino dienophiles in intermolecular and intramolecular aza Diels-Alder reactions affording tetrahydropyridines and indolizidines. The [alpha]-amino nitrile cycloadducts are versatile synthetic intermediates that participate in a variety of stereoselective transformations to further elaborate the six-membered ring. This thesis describes the scope of the intermolecular [4 + 2] cycloaddition of N-benzyliminoacetonitrile with unactivated and activated dienes, as well as, the synthetic elaboration of the cycloadducts. This thesis also describes the worked performed to complete the total syntheses of indolizidines (-)- 235B', (-)-235B", and (+)-235B" using the aza Diels-Alder reaction of an iminoacetonitrile as the key step.

Book excerpt: The series Topics in Current Chemistry presents critical reviews of the present and future trends in modern chemical research. The scope of coverage is all areas of chemical science including the interfaces with related disciplines such as biology, medicine and materials science. The goal of each thematic volume is to give the non-specialist reader, whether in academia or industry, a comprehensive insight into an area where new research is emerging which is of interest to a larger scientific audience. Each review within the volume critically surveys one aspect of that topic and places it within the context of the volume as a whole. The most significant developments of the last 5 to 10 years are presented using selected examples to illustrate the principles discussed. The coverage is not intended to be an exhaustive summary of the field or include large quantities of data, but should rather be conceptual, concentrating on the methodological thinking that will allow the non-specialist reader to understand the information presented. Contributions also offer an outlook on potential future developments in the field. Review articles for the individual volumes are invited by the volume editors. Readership: research chemists at universities or in industry, graduate students

Book excerpt: The rate of advance in areas of science is seldom constant. Usually certain fields effloresce with activity because of the ~ealization that solutions are possible to long standing important problems. So it is now with asymmetric catalysis, a field which promises to change profoundly the strategic thinking of synthetic chemists. As this Report will show, reagents which can induce catalytic enantiocontrol of chemical transformations could represent the ultimate synthetic method. Nearly all synthetic strategies of complex molecules involve steps which require enantiocontrol and, in many cases, a specific catalytic transformation embodying enan tiocontrol has enormous advantages in terms of the rate and economy of the reaction. Because asymmetric catalysis is in a formative stage, workers with different backgrounds have joined the field. This Workshop had representatives with organometallic, organic, structural, kinetic, enzymatic, microbiological and industrial backgrounds. Each had his own perspective and this Report represents a consensus of this group of eleven people. The result is probably as compre hensive and balanced a view of the subject as is possible at present. It is hoped that those who have until now had but a glancing interest in asymmetric catalysis will find this Report a useful indication of its present state. We believe that asymmetric catalysis will have an increasing impact on the development of chemistry and will eventually dominate much of synthetic and industrial chemistry.

This book was released on 2017-01-03 with total page 445 pages. Available in PDF, EPUB and Kindle. Book excerpt: The metal-catalyzed amination of aryl and alkenyl electrophiles has developed into a widely used methodology for the synthesis of natural products, active pharmaceutical ingredients, agricultural chemicals, and materials for molecular electronics. Copper catalysts promote the coupling of a wide range of nitrogen nucleophiles, including amines, amides, and heteroaromatic nitrogen compounds with aryl and alkenyl halides. The reactivity profile of copper catalysts is complementary to that of palladium catalysts in many cases. Copper catalysts are highly effective with less nucleophilic nitrogen nucleophiles, such as amides and azoles, whereas palladium catalysts are more effective with more nucleophilic amine nucleophiles. Copper is an attractive alternative to palladium due to its significantly lower cost. In addition, high activity palladium catalysts require expensive and often air-sensitive ligands, whereas the modern copper systems use relatively stable and inexpensive diamine or amino acid ligands. Copper-catalyzed C N coupling reactions are tolerant of a wide range of functional groups and have been applied to the synthesis of a variety of complex natural products. Significant work has also been done to understand the mechanism of these reactions. Current mechanistic understanding of these methodologies is covered in this monograph. The contents of the book are taken from the comprehensive review of the topic in the Organic Reactions series. Optimal experimental conditions for the amination of aryl and alkenyl halides with all classes of nitrogen nucleophiles are presented. Specific experimental procedures from the literature are provided for the major classes of copper-catalyzed C N coupling reactions. A tabular survey of all examples of Cu-catalyzed arylation and alkenylation of nitrogen nucleophiles is presented in 35 tables organized by nitrogen nucleophile and electrophilic coupling partner. The literature is covered through December 2015 and provides 300 recent citations to supplement the 680 citations of the original hardbound chapter. These latest literature references have been collected in separate sections according to the sequence of the tables in the tabular survey section. In each of the sections, the individual citations have been arranged in alphabetic order of the author names. Copper-Catalyzed Amination of Aryl and Alkenyl Electrophiles is intended to provide organic chemists with an accessible, but detailed, introduction to this important class of transformations.
