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 …
