Total synthesis of indole alkaloids: pt. 1. Asymmetric synthesis of (-)-ibogamine. pt. 2. An approach toward the synthesis of koumine

Creator:

Choi, Younggi

Abstract:

PART I. The preparation of (-)-ibogamine (1) in fourteen steps from benzoquinone and in 10% overall yield is a powerful illustration of the value of the asymmetric Diels-Alder reaction as a starting point in a multistep synthesis. All four cycloadducts, 70, 77, 84 and 96, obtained with the (S)-BINOL-TiCl₂ complex...

The synthesis and chemistry of strained bicyclic systems

Creator:

Scerbo, Louis

Abstract:

A facile route to bicyclo(2.1.1)hexanes was developed involving the intramolecular photocyclization of 1, 5-hexadien-3-one to bicyclo(2.1.1)hexan-2-one. A study of the chemistry of bicyclo-(2.1.1)hexan-2-one was undertaken. Deuterium exchange and borohydride reduction demonstrated the strain present in the ketone. Further evidence was obtained from the failure to introduce substituents alpha to the...

The study of fluo-tantalum species by solvent extraction

Creator:

Coker, Marjory Carol

Abstract:

The extraction of tantalum fluoride complexes by large cationic extractants (tetraphenylarsonium ion, TPA, and crystal violet) and by methyl isobutyl ketone (MIBK) has been investigated as a function of fluoride concentration using ¹⁸² Ta as tracer. Extractions by the cationic extractants into chloroform were carried out in the absence of...

The separation and purification of the fatty and hydroxy fatty acids of white fir bark wax

Creator:

Carroll, Karen Esther

Abstract:

This investigation was undertaken to develop a procedure by which the fatty acids could be separated from the hydroxy fatty acids of bark waxes. The specific hexane-insoluble, benzene-soluble wax used in this research was obtained from the bark of white fir, Abias concolor, (Lindl. and Gord.). The acids were removed...
