Available in PDF, EPUB and Kindle. Book excerpt: In the Diels-Alder reaction of hexachlorocyclopentadiene and alpha-methyl-styrene, the cistrans ratio of deuterium in the beta-position of the alkene remains unchanged in the adduct. The reactions of cis- and trans-1,2-dichloroethylene with cyclopentadiene have been found to be at least 99.5% stereospecific. Since these systems were designed to favor the diradical intermediate which might be involved in a two-step mechanism, the observed high degree of specificity is best accounted for on the basis of a concerted, one-step mechanism.

Clark and published by . This book was released on 2008 with total page 560 pages. Available in PDF, EPUB and Kindle. Book excerpt: Although the inverse electron demand Diels-Alder reaction of N-sulfonyl-1-aza-1,3-butadienes with electron-rich dienophiles has been extensively examined in our laboratory, we sought to control the absolute configuration of the tetrahydropyridine products and thereby extend the utility of the methodology. The first detailed study of a room temperature asymmetric Diels-Alder reaction of N-sulfonyl-1-aza-1,3-butadienes enlisting a series of nineteen enol ethers bearing chiral auxilaries is described herein. Many of these auxilaries provided highly diastereoselective reactions (in both the endo and facial sense) largely the result of a highly organized [4+2] cycloaddition transition state. Three readily accessible and previously unexplored butyrolactone and pyrrolidinone auxilaries rationally emerged from the studies and provide exceptional selectivities (up to 49:1 endo:exo and 48:1 facial).

Available in PDF, EPUB and Kindle. Book excerpt: Hydrocarbons and their transformations play major roles in chemistry as raw materials and sources of energy. Diminishing petroleum supplies, regulatory problems, and environmental concerns constantly challenge chemists to rethink and redesign the industrial applications of hydrocarbons. Written by Nobel Prize-winner George Olah and hydrocarbon expert Árpád Molnár, the completely revised and expanded Second Edition of Hydrocarbon Chemistry provides an unparalleled contemporary assessment of the field, presenting basic concepts, current research, and future applications. Hydrocarbon Chemistry begins by discussing the general aspects of hydrocarbons, the separation of hydrocarbons from natural sources, and the synthesis from C1 precursors with recent developments for possible future applications. Each successive chapter deals with a specific type of hydrocarbon transformation. The Second Edition includes a new section on the chemical reduction of carbon dioxide–focusing on catalytic, ionic, electrocatalytic, photocatalytic, and ezymatic reductions–as well as a new chapter on new catalysts and activation methods, combinatorial chemistry, and environmental chemistry. Other topics covered include: Major processes of the petrochemical industry, such as cracking, reforming, isomerization, and alkylation Derivation reactions to form carbon-heteroatom bonds Hydrocarbon oxidations Metathesis Oligomerization and polymerization of hydrocarbons All chapters have been updated by adding sections on recent developments to review new advances and results. Essential reading for practicing scientists in industry, polymer and catalytic chemists, as well as researchers and graduate students, Hydrocarbon Chemistry, Second Edition remains the benchmark text in its field.

Available in PDF, EPUB and Kindle. Book excerpt: The intramolecular Diels-Alder reaction is widely recognized as a powerful and versatile method for the assembly of complex bicyclic structures in synthetic organic chemistry and has been utilized as a key step in the total syntheses of a number of interesting biologically active natural products. We have studied the use of siloxacyclopentene constrained trienes as a method to control diastereofacial selectivity in the intramolecular Diels-Alder reaction. The siloxacyclopentene constraints could be formed under mild conditions and attached to either the diene or dienophile units of a variety of trienes. These constrained trienes underwent intramolecular Diels-Alder reactions to give cycloadducts with the oxygen contained in the siloxacyclopentene exclusively in an anti-configuration relative to the ring fusion proton. Suitably chosen dienophile activating groups and optimized conditions for cyclization allowed for high levels of selectivity for either cis - or trans -fused cycloadducts in the case of siloxacyclopentenes contained within the diene, while siloxacyclopentenes constraints attached at the dienophile gave exclusively the trans-fused cycloadducts. A siloxacyclopentene constrained tetraene was then utilized in a concise, stereoselective synthesis of the decahydrofluorene core common to the hirsutellones. Synthetic efforts targeting the completion of the hirsutellones via a common biosynthetic intermediate were pursued utilizing a macrobenzannulation strategy. This strategy was abandoned due to inability to prepare a suitable benzannulation precursor. Later a strategy of first forming a five membered ring containing analogue was also pursued, but failed due to an inability to convert a suitable ester to the corresponding furan or thiophene.
