This new volume substantially updates the original pyridazines volume which was published in 1973. Announcing the latest volume in the successful and prominent Chemistry of Heterocyclic Compounds Series.
This book serves as a supplement to The Pyrazines, Volume 41 of theChemistry of Heterocyclic Compounds series. It covers theliterature published between 1979 and 2000, and–together withVolume 41–provides a complete, up-to-date reference forheterocyclic chemists. It emphasizes practical approaches topyrazine chemistry, offers a full appendix of all simple pyrazinesup to 2000, and features detailed coverage of the following topics: Systematic descriptions of all primary synthetic routes topyrazines Other preparative routes to alkylpyrazines and theirreactions Halogenopyrazines and their synthetic uses Oxypyrazines and trivial names for pharmaceutical oragrochemical pyrazines Thiopyrazines Amino-, nitro-, and other similar pyrazines and theirreactions Pyrazinecarboxylic acids and their derivatives The supplement features extensive cross-references to theoriginal volume and uses chemical nomenclature as per current IUPACrecommendations
This is the second volume of a first-of-its-kind four-volume book set that provides readers with up-to-date information on α-amino acids, the potential challenges in working with α-amino acids, the protecting groups for the carboxyl, amino and side chain groups of the amino acids, and the most popular heterocyclic compounds that are originating from alpha-amino acids. These heterocyclic compounds include hydantoins, thiohydantoins (including 2-thiohydantoins, 4-thiohydantoins, 2,4-dithiohydantoins), 2,5-diketopiperazines, N-carboxyanhydrides, N-thiocarboxyanhydrides, sydnones, sydnonimines, azlactones, pseudoazlactones, and oxazolidin-5-ones. This is the first resource to comprehensively collect all the heterocycles that can be directly prepared from α-amino acids. In addition, almost all kinds of synthetic methods for a particular type of heterocycles from alpha-amino acids are included, along with the detailed mechanistic discussions and experimental procedures. In Volume 2: Hydantoins, Thiohydantoins, and 2,5-Diketopiperazines compiles the three IUPAC accepted nomenclature systems for heterocyclic compounds, which will be very useful for readers working in the heterocyclic chemistry field for giving synthesized molecules their correct names. In addition, three groups of heterocyclic compounds, i.e., hydantoins, thiohydantoins (including 2-thiohydantoin, 4-thiohydantoin and 2,4-dithiohydantoin), and 2,5-diketopiperazines, have been organized with updated literature information. Particularly, all three groups of heterocyclic compounds have demonstrated many important biological activities, particularly anticancer and antibacterial activities. On the other hand, these three groups of heterocycles can be applied as substrates to make other chemical derivatives, particularly novel unnatural amino acids. All their reactivities have been compiled and updated. The other volumes include: Volume 1: Protecting Groups Volume 3: N-Carboxyanhydrides, N-Thiocarboxyanhydrides, and Sydnones Volume 4: Azlactones and Oxazolidin-5-ones All together, this unique 4-volume set thoroughly covers the two types of heterocyclic compounds that are originated from alpha-amino acids, providing carefully compiled updated information with detailed examples. The author has shared many thoughtful insights based on his strong background in physical organic chemistry. The volumes will be highly valuable for graduate students and senior students, as well as for professors and researchers working in the field of medicinal and pharmaceutical chemistry, organic chemistry, organic synthesis, heterocycles, and proteins and peptides.
This book provides the most comprehensive, current reference on the synthetic chemistry of cinnolines and phthalazines. Applications to the syntheses of natural products and other chiral compounds are described. Volume 64 contains chapters exploring the following topics: * Primary Syntheses of Cinnolines * Cinnoline, Alklycinnolines, and Arylcinnolines * Halogenocinnolines * Oxycinnolines * Thiocinnolines * Nitro-, Amino-, and Related Cinnolines * Cinnolinecarboxylic Acids and Related Derivatives * Primary Syntheses of Phthalazines * Phthalazine, Alklyphthalazines, and Arylphthalazines * Halogenophthalazines * Oxyphthalazines * Thiophthalazines * Phthalazinecarboxylic Acids and Related Derivatives * An Appendix of Tables of Simple Cinnolines and Simple Phthalazines
This fourth volume of the Supplement Series supplying the Main Volumes of the series "Perfluorohalogenoorgano Compounds of Main Group Elements" (Part 1 to 9) covers the heterocyclic compounds of nitrogen as the last main group element of this series. Compounds of the elements of main group 1 to 4, 6 (without 0), and of P, As, Sb, Bi, and I are presented in the Supplement Volumes 1 to 3. Concept, organization, and selection as to coverage of the material are the same as in the preceeding volumes. Title compounds are either newly synthesized ones or those compounds already referred in the Main Volume Parts 5 and 6 for which new facts have been published. I wish to thank Prof. Dr. Dr. h. c. E. Fluck and his co-workers for their excellent cooperation and many colleagues for providing reprints and patents. One of us (U. Niemann) thanks Philips GmbH Forschungslaboratorium Aachen for generous support. November 1987 Bochum, A.

New edition of the acclaimed reference series, Houben-Weyl. This new ed. is published in English and is available in both print and electronic formats. Clear and systematic, Science of Synthesis provides practical solutions and offers a route through the mass of information available in the primary literature. This one-stop reference tool is: Comprehensive: contains synthetic models selected by world-renowned experts, with full experimental procedures and background information. Reliable: the international editorial board is made up of distinguished chemists with unparalleled experience and competence. Logical and easy-to-navigate: information is organized in a hierarchical system based on the compound or functional group to be synthesized. Authoritative: critically evaluates the preparative applicability and significance of the synthetic methods. Wide-ranging: considers methods from journals, books, and patent literature from the early 1800s up to the present day and presents important synthetic methods for all classes of compounds.
A team of editors have selected important and interesting compounds which have appeared in the literature since publication of volume 8. Volume 9 contains approximately 1200 compounds which are mostly new entries, plus a selection of data on compounds already listed in volumes 1-8. This represents literature coverage to mid-1995 and extends the range of the "Dictionary of Inorganic Compounds" to over 50,000 compounds.
