Abstract:

Described in this thesis is the development of a key Diels-Alder reaction for use in a total synthesis of the potently immunosuppressant marine alkaloid palau'amine. This study focuses on the originally proposed structure of palau'amine. The strategy utilizes a computationally designed thiohydantoin dienophile as the 2pi component and a thermally stable 2-silyloxy-5-(silyloxymethyl)cyclopentadiene as the 4pi component in the critical Diels-Alder reaction. Essential to the design and study of these partners was the use of computational density functional theory (DFT) predictions.<br>Four famili

Abstract:

Many natural products contain a tetramic acid (pyrrolidine-2,4-dione) ring system as an integral part of their structure. They exhibit a wide range of biological activities and are structurally diverse, making them an attractive target for the synthetic chemist. The pyrroindomycin antibiotics are an example of such natural products which contain a spirotetramate core. Studies towards the total synthesis of the pyrroindomycins are described within this thesis, which involve inter- and intra- molecular Diels-Alder approaches towards the synthesis of the spirotetramate core of the natural product

Abstract:

This thesis describes the investigation of the Diels-Alder reaction of the imine (140) with the diene (141) to give four products (142,143,156, 157). At low temperatures the enone (156) is the major product while at ambient temperature the bicyclic compounds (142) and (143) predominate. The reaction is highly solvent dependent, with the best results being obtained in benzene solution. Lewis acids appear to have little effect on the course of the reaction. The reaction of the imine (140) with the TBDMSO diene (159) gives the silyl enol ethers (160) and (161) as well as the above four products.

Abstract:

The corrosion of infrastructure imposes a significant monetary cost, and at times human cost, upon society. Methods to improve corrosion resistance of materials are described herein which utilize the reversibility of the Diels-Alder reaction to impart thermal responsiveness upon materials. Such stimuli responsiveness can potentially play a role in self healing properties which lead to reduced cracking and thus increased corrosion protection. Reversible Diels-Alder chemistry was utilized to manipulate the surface energy of glass substrates. Hydrophobic dieneophiles were prepared and attached

Abstract:

Fluoropolymers have useful properties including high thermal stability, chemical resistance, low dielectric constants, and both hydrophobic and oleophobic character, as compared to non-fluorinated analogues. Meanwhile, Diels-Alder polyphenylenes (DAPPs) are known for thermal stability as well as their rigid structure and glassy physical characteristics, which have led to a variety of film and membrane applications. This dissertation merges these two fields by demonstrating a novel and general synthetic approach to highly fluorinated DAPPs. These polymers are expected to retain the physical cha

New calcu- lation methods were developed and tested. This was the focus of the first part of the thesis, by choosing a small system, extensive and heavy calculations could be done with CBS-QB3.

For this reason, considerable eﬀort has been invested in developing eﬃcient and stereoselective organo- and biocatalysts. However, Diels-Alder is a virtually unknown reaction in Nature, and to engineer an enzyme into a Diels-Alderase is therefore a challenging task.
