This book was released on 2016 with total page 141 pages. Available in PDF, EPUB and Kindle. Book excerpt: In Chapter 1, rearrangements of 4-substituted bicyclo[2.2.2]oct-2-enyl-5-selenophenyl esters are explored. Reduction of the esters under radical-generating conditions initially generates a bicyclo[2.2.2]oct-5-en-2-yl radical which can rearrange to a bicyclo[3.2.1]oct-6-en-2-yl radical via a cyclopropylcarbinyl radical. Although the bicyclo[3.2.1]octene system exhibits greater strain than does the bicyclo[2.2.2]octene system, radical-stabilizing substituents can reverse this preference. The product ratios are influenced by the interplay of ring strain and radical stability. In addition, the rearranged products favored the equatorial over the axial isomers, which can be explained by torsional steering. In Chapter 2, different approaches to the synthesis of the optically active bicyclo[2.2.2]octane-2,5-diones are presented. A stereoselective Diels-Alder cycloaddition was explored to construct the bicyclo[2.2.2]octane skeleton in an efficient manner. This approach was hindered by unexpected polymerization and lack of stereoselectivity. A different method of synthesizing the optically active bicyclo[2.2.2]octane-2,5-dione featuring a diastereoselective 1,4-addition is also presented. In Chapter 3, progress toward the total synthesis of parthenolide is described. The synthetic route relies on ring-closing metathesis to close the 10-membered carbocycle of the natural product. The efforts leading up to and including the key ring-closing step are described. Specific attention is given to different methods for overcoming the difficulties associated with medium-sized ring formation.

Available in PDF, EPUB and Kindle. Book excerpt: During Recent Years, Stereochemistry Has Undergone A Phenomenal Growth Both In Theory And Practice, With A Concomitant Increase Of Interest Among The Organic Chemists, Biological Chemists, Medicinal Chemists, And Pharmacologists. The Present Text Provides An Up-To-Date, Coherent; And Comprehensive Account Of The Subject Starting From The Fundamentals And Leading Up To The Latest Development As Far As Practicable. Emphasis Has Been Placed On Symmetry-Based Approach To Molecular Chirality, Stereochemical Terminologies (Modern Stereochemistry Is Replete, With Them), Topicity And Prostereoisomerism, Conformational Analysis, Dynamic Stereochemistry, Chiroptical Properties, And Assignment Of Absolute Configuration To Chiral Molecules.Dynamic Stereochemistry Has Been Discussed With Reference To Conformation-Reactivity Correlation, Stereoselective Syntheses, And Pericyclic Reactions. A Large Cross Section Of Organic Reactions With Stereochemical Implication Has Been Incorporated. Attempts Have Been Made To Familiarise The Readers With Modem Instrumental Techniques, Nuclear Magnetic Resonance In Particular, Used For Stereochemical Investigation. Each Chapter Is Provided With A Summary Which Highlights The Main Points Of The Text. Selective References, Mostly Of Textbooks, Monographs, Review Articles, And Significant Original Papers Have Been Given Extending Sometimes To Early 1991.The Book Is Expected To Fulfil The Long-Felt Need For A Comprehensive Text On Modern Organic Stereochemistry Which Is Conspicuously Absent Since The Publication Of Professor Eliels Book In 1962. The Text May Be Adopted At Any Stage Of The University Teaching And At The Same Time Be Useful To The Practising Organic Chemists.

Available in PDF, EPUB and Kindle. Book excerpt: In 1965 a book by P. Bartlett appeared under the title "The Nonclassical Ions" 1). The book is a collection of papers reprinted from various journals. The many reviews that have appeared since 2-22) are either antiquated (the book published in 1972 12) covers the literature mainly before 1968) or relatively biased (e.g., 3.4,10» on brief 2, 7,11). This review attempts to discuss the various points of view on the "nonclassical" carbocations. The main point is to establish the relative role of "nonclassical" and "classical" ions in various chemical processes. The author has followed P. Bartlett's advice 1) that when setting forth the achievements of the human mind one should see how we came to the modern understanding of a given problem (" ... how we know what we know"). The theory of "nonclassical" ions offers an explanation of many unique chemical, stereochemical and kinetic peculiarities of bicyclic compounds. It has expanded our knowledge on chemical bonds in carbocations by introducing electron-deficient bonds (as in boron hydrides). It has accounted for many rearrangements of stable cations. As a "side" result our knowledge has been extended about ionization processes in a solution, as well as about stereochemical methods. 2 Main Terms of Nonclassical Carbocations In 1939 Hevell, Salas and Wilson 23) assumed an intermediate, "bridge" ion 2 to be formed when camphene hydrochloride 1 is rearranged into isobornyl chloride 3. This happened 17 years after Meerwein first postulated the intermediate formation of "carbonium" ions in chemical reactions.
