Reactions Of Difunctional Esters With Benzyl 2-Amino-4,6-0- Benzylidene-2-Deoxy-D-Glucopyranosides, Fred Robert Seymour

University of the Pacific Theses and Dissertations

This research is primarily interested in investigating the reactions of benzyl 2-amino-4,6-0-benzylidene-2- deoxy-D-glucopyranoside (I) with various esters. The advantage offered by this sugar is that an alcohol and an amine group are in close proximity, allowing studies of intermolecular vs. intramolecular reactions and observation on anchimeric assistance in intramolecular reactions.

Strained Cycloallenes And Silver Ion Assisted And Unassisted Solvolysis Of Some N,N-Dibromobicyclo(N-3.1.0)Alkanes, Franklin Maurice Boyden

University of the Pacific Theses and Dissertations

The strained cyclic allene intermediates of 1,2-cyclohexadiene, 1,2-cycloheptadiene and 1,2-cyclooctadiene have been successfully generated by the debromination of their corresponding 2,3-dibromocycloalkenes. Evidence for their intermediate existence was obtained by trapping them with the Diels-Alder trapping agent 2,5-diphenyl 1-3,4-benzofuran and by isolating the corresponding addition products.

The goal of this study was to generate the transitory cyclic allenes 1,2-cyclooctadiene, 1,2-cycloheptadiene and 1,2-cyclohexadiene and to investigate some aspects of their chemistry. Evidence for the intermediate existence of these strained cyclic allenes has been found by generating them by the debromination of their corresponding 2,3-dibromocycloalkenes and by trapping the generated cycloallene intermediates with …

The Preparation And Determination Of Some Of The Properties Of The Dicarboxylic Amino Acid Chelates Of Platinum(Ii) And Palladium(Ii), Gordon Harold Williams

University of the Pacific Theses and Dissertations

It is surprising that no one has considered that coordination might have some effect on the strength of the acid group. It is the intent of this study to fill this gap in the knowledge of amino-acid chemistry.

At about the time this study began on the effect of chelation on the strength of the uncomplexed acid group, the next two higher homologs of these dicarboxylic amino acids became commercially available. It was, therefore, decided that the problem of this research should be expanded to include all four of the acidic amino acids.

The research problem was also defined to …
