Studies on terpenoids from tecoma stans and eperua falcata
Thesis
Dickinson, E. M. (1968). Studies on terpenoids from tecoma stans and eperua falcata

Part I Summary The chemistry and biosynthesis of cyclopentanoid monoterpene alkaloids is reviewed. The isolation of pyrindane and perhydropyrindane alkaloids from several samples of Teooma stans (Juss) and their separation by column and preparative...

Synthesis and stereochemistry of some 9,10-dihydroanthracenes
Thesis
(1968). Synthesis and stereochemistry of some 9,10-dihydroanthracenes

The geometry of the 9,10-dihydroanthracene system is discussed, leading to an explanation of the relevance of conformational analysis for 9,10-dihydroanthracene derivatives. Synthetic routes to 9,10-dialkyl- 9,10-dihydroanthracene-9,10-diols are revi... Read More about Synthesis and stereochemistry of some 9,10-dihydroanthracenes.

A study of beam masers and alternate gradient focusing of neutral particles
Thesis
(1968). A study of beam masers and alternate gradient focusing of neutral particles

An ammonia beam maser is constructed and its basic characteristics established. An attempt is made to put the theory of state selection and focusing of molecules in a maser in a generalized form so as to include the case of lower state focusing as we...

Electron spin resonance studies of myoglobin at millimeter wavelengths
Thesis
(1968). Electron spin resonance studies of myoglobin at millimeter wavelengths

The work described in this thesis is concerned with the development of millimeter wave electron spin resonance spectrometers, and the application of such spectrometers to a study of the ferric ion in myoglobin. Firstly an outline of the basic theor... Read More about Electron spin resonance studies of myoglobin at millimeter wavelengths.

Synthetic approaches to 9-azasteroids
Thesis
(1968). Synthetic approaches to 9-azasteroids

An account is given of total syntheses of azasteroids, syntheses of 4-piperidones, and also syntheses of 2-quinolizidones. l,2,3,4,5,6-Hexahydro-3-oxo-4aH-benzo[c]quinolizine was prepared and methylation shown to occur in the 2-position which was o...

An electron paramagnetic resonance study of ferric iron in strong crystal fields
Thesis
Pontin, R. G. (1968). An electron paramagnetic resonance study of ferric iron in strong crystal fields

The work described in this thesis is concerned with the measurement of the large zero-field splittings of ferric iron substituted into a number of mixed metal oxide host lattices. The first chapters give an outline of the crystal field approach... Read More about An electron paramagnetic resonance study of ferric iron in strong crystal fields.

Synthesis, reactions, and mass spectra of some indolizines
Thesis
Stanyer, J. (1968). Synthesis, reactions, and mass spectra of some indolizines

The methods of synthesis and known properties of indolizines are reviewed. A number of indolizine compounds substituted in both the 5 membered and 6 membered rings have been prepared by known synthetic routes. The use of an ion exchange resin to...

1-alkoxyvinyl esters as synthetic intermediates
Thesis
Thomas, J. A. G. (1968). 1-alkoxyvinyl esters as synthetic intermediates

The chemistry and properties of 1-alkoxyvinyl esters and of cyclopropanones are reviewed. A number of 1-ethoxyvinyl esters have been isolated, both for their intrinsic interest and also because of their value as synthetic intermediates. Phthaloyl...
