Available in PDF, EPUB and Kindle. Book excerpt: This current and five previous volumes (Volumes 133, 135, 144, 155, 178) convincingly demonstrate the vast applications of small rings in modern Organic Synthesis. Such applications range from total syntheses of cyclopropyl-group-containing natural products and non-natural biologically active compounds or compounds with other important properties (e.g. liquid crystalline) via syntheses of cyclopropyl analogues of natural and non-natural physiologically active compounds, e.g. peptidomimetics, to the use of cyclopropyl groups as reactive subunits in so-called composite functional groups. This current volume covers a survey of the wide range of biological activities of cyclopropyl-containing compounds, up-to-date comprehensive reviews on the multiple applicabilities of two multifunctional small ring building blocks - methyl-2-chloro-2-cyclopropylidene acetate and bicyclopropylidene - in Organic Synthesis as well as a striking new approach to cyclopentenones from easily accessible 1-ethynylcyclopropanols, which is rather general and favorably complements other cyclopentenone syntheses.

Available in PDF, EPUB and Kindle. Book excerpt: Since the pioneering work by Sarel and co-workers on the iron carbonyl p- moted transformation of vinylcyclopropanes and related compounds [1],a - riety of transition metal complexes have been examined to achieve effective - tivation of the vinylcyclopropane-cyclopentene rearrangement which usually requires pyrolytic conditions. These reactions have been applied to natural product synthesis in some cases and have already been reviewed in several - cellent articles [2–4]. Contrary to the well-established chemistry of the vinylcyclopropanes, the corresponding reactions of alkynyl- and propadienylcyclopropanes have not, until recently,received much attention.We present here a summary of the recent efforts towards the development of transition metal promoted transformation of these molecules with a brief survey of the corresponding thermal reactions. 2 Rearrangement of Alkynylcyclopropanols Unlike the well-known chemistry of the vinylcyclopropane-cyclopentene - arrangement, there is no general method for the rearrangement of alkyn- cyclopropane to cyclopentene derivatives.One specific example is the pyrolysis of 1-ethynyl-2-methylcyclopropane to methylenecyclopentene and other c- pounds [5].At 530°C, 1-ethynyl-2-methylcyclopropane (1) undergoes a [1,- hydrogen shift to give hexa-1,2,5-triene ( 2),which further isomerizes to met- lenecyclopentenes 3 and 4 in 38 and 29% yield,respectively (Scheme 1).

Book excerpt: The second edition of Comprehensive Organic Synthesis—winner of the 2015 PROSE Award for Multivolume Reference/Science from the Association of American Publishers—builds upon the highly respected first edition in drawing together the new common themes that underlie the many disparate areas of organic chemistry. These themes support effective and efficient synthetic strategies, thus providing a comprehensive overview of this important discipline. Fully revised and updated, this new set forms an essential reference work for all those seeking information on the solution of synthetic problems, whether they are experienced practitioners or chemists whose major interests lie outside organic synthesis. In addition, synthetic chemists requiring the essential facts in new areas, as well as students completely new to the field, will find Comprehensive Organic Synthesis, Second Edition, Nine Volume Set an invaluable source, providing an authoritative overview of core concepts. Winner of the 2015 PROSE Award for Multivolume Reference/Science from the Association of American Publishers Contains more than170 articles across nine volumes, including detailed analysis of core topics such as bonds, oxidation, and reduction Includes more than10,000 schemes and images Fully revised and updated; important growth areas—including combinatorial chemistry, new technological, industrial, and green chemistry developments—are covered extensively
Download or read book Small Ring Heterocycles Volume 42 Part 3 written by Alfred Hassner and published by John Wiley & Sons. This book was released on 2009-09-15 with total page 887 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Chemistry of Heterocyclic Compounds, since its inception, has been recognized as a cornerstone of heterocyclic chemistry. Each volume attempts to discuss all aspects – properties, synthesis, reactions, physiological and industrial significance – of a specific ring system. To keep the series up-to-date, supplementary volumes covering the recent literature on each individual ring system have been published. Many ring systems (such as pyridines and oxazoles) are treated in distinct books, each consisting of separate volumes or parts dealing with different individual topics. With all authors are recognized authorities, the Chemistry of Heterocyclic Chemistry is considered worldwide as the indispensable resource for organic, bioorganic, and medicinal chemists.
