New Methodologies and Catalysts for the Diels-Alder Reaction
Author: Leah Brigit Cleary

Category :
Languages : en
Pages : 579
Book Description
This thesis documents progress on five distinct projects pertaining to advancing methodologies and the synthetic utility of the Diels-Alder reaction. The first methodical study used a microwave reactor as convenient and safe heating source to induce the type 2 intramolecular Diels-Alder reaction. The second methodology involves the synthesis and study of bis-borane Lewis acids as chiral catalysts of intermolecular Diels-Alder reactions and ionic Diels-Alder reactions. A computational study to determine the origins in regio- and diastereoselectivity of the N-acylnitroso type 2 intramolecular Diels-Alder reaction accompanies our synthetic efforts toward the total synthesis of the Stemona alkaloid, ( - )-stenine. Finally, progress toward the total synthesis of the welwitindolinone alkaloids, N-methyl welwitindolinone C isothiocyanate and N-methyl welwitindolinone B isothiocyanate, is reported.

Intramolecular Diels-Alder and Alder Ene Reactions
Author: Douglass F. Taber
Publisher: Springer
ISBN: 9783642692352
Category : Science
Languages : en
Pages : 0
Book Description
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.
