This book was released on 2012-12-06 with total page 106 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Diels-Alder reaction has long been a powerful tool in organic synthesis. In recent years, the Alder ene reaction has also achieved some prominence. From the beginning, it was apparent that the intramolecular variants of these reactions would be feasible. Many such have been reported, but the results are widely scattered in the chemical literature. This volume is an attempt to synthesize results observed to date, and to suggest directions for future development. One of the limiting factors in the application of the intramolecular Diels Alder reaction has been the development of methods for the preparation of the requisite trienes. The fIrst chapter of this volume summarizes methods for the preparation of dienes and dienophiles. Examples representative of every general approach to 1,3-dienes and to dienophilic functional group combinations have been included. There are two questions one might ask in considering the prospective cyclization of a given triene: what are the factors that govern the rate of cyclization? and, for cyclizations that lead to the creation of one or more new chiral centers, what are the factors that govern diastereoselectivity? These questions are addressed in Chapter Two. The third chapter is devoted to the all-carbon intramolecular Alder ene reaction. The tables in that chapter summarize all examples that could be found in the literature through 1981, with several additional examples from 1982. Leading references to heterocyclic ene reactions are also included in this chapter.

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.

This book was released on 2014 with total page 204 pages. Available in PDF, EPUB and Kindle. Book excerpt: Intramolecular Diels-Alder (IMDA) reactions are an important class of reactions in synthetic organic chemistry for the rapid construction of polycyclic frameworks. Three classes of IMDA reactions were investigated synthetically and computationally: 1) all-carbon type 1 IMDA reactions, 2) N-acylnitroso type 2 IMDA reactions, and 3) cyano-azadiene IMDA reactions. The first class was implemented in research toward the total synthesis of maoecrystal Z and isopalhinine A. The second class was studied computationally to understand the origins of regio- and stereochemistry in these reactions. The third class was investigated in the context of indolizine and quinolizidine synthesis.
