A method for the isolation of canavanine by ion exchange

Creator:: Fujiwara, Allan
Abstract:: In 1959 Kitagawa discovered and isolated the amino acid, canavanine. Since its discovery much interest has been centered on this amino acid because of its biological aspects; e.g. canavanine has been shown to inhibit the growth of bacteria, viruses, protozoa, and cancer cells. The occurrence of canavanine is widespread in...

A study of factors leading to N, N-diacetylation of aminopyrimidines

Creator:: Carson, Bonnie L.
Abstract:: Although 4- and 5-diacetamidopyrimidines have been reported in the literature within the past eleven years, it was not until 1965 that a 2-diacetamidopyrimidine was reported. The current investigation was undertaken to determine whether other 2-diacetamidopyrimi-dines could be synthesized and what the effect of various nuclear substituents would be on the...

A low power zone-refining system for semiconductor materials

Creator:: Christensen, Gerald Albert
Abstract:: This paper presents an investigation of the power needs and impedance-matching techniques involved when heating small charges of relatively high-resistivity semiconductor materials. Topics of discussion also include a brief section on the theoretical basis for zone refining, relative merits of resistance and induction heating, travel mechanism requirements, and work coil...

Willamette Valley farm deferral accounts under Oregon Revised Statute 308.370

Creator:: Christensen, Larry Dale
Abstract:: This research is an effort to appraise the results of the 1963 legislation, especially in terms of the spatial aspect. Has it achieved the desired purpose? How many, and what size of farms are involved? Where are these farms located? The research field work resulted in a definitive map showing...

The study of the influence of the nitro substituent on the hydrazinolysis of certain substituted 5-nitropyrimidines

Creator:: Stahl, Quade Russell
Abstract:: The unique reaction between 4, 6-dimethoxy-5-nitropyrimidine and methylhydrazine was investigated. The reaction product was identified as 4-hydrazino-6-hydroxypyrimidine from (a) spectral data, (b) by direct synthesis of the product via 4-chloro-6-hydroxypyrimidine and hydrazine, and (c) by conversion of the product to the known 4-amino-6-hydroxypyrimidine using Raney nickel. The product was not...

An investigation of the reduction products of 4-amino-2, 6-dichloropyrimidine by catalytic hydrogenation

Creator:: Leutzinger, Eldon Edward
Abstract:: In recent years nuclear reduction of pyrimidines by catalytic hydrogenation in acid media has been considered a possible synthetic method for the preparation of substituted tetrahydropyrimidines. This technique has the advantage of simplicity over the older condensation methods and is limited only by the preparation of the appropriately substituted pyrimidines....

The investigations of the methods for the reduction of chloropyrimidines

Creator:: Ladpli, Vimolvan
Abstract:: This thesis investigated on the dehalogenation of 2, 4- dichloropyrimidine in various different conditions. These conditions were changed by varying the solvents, the amount of catalysts and the hydrogen chloride acceptors in order to study the effects on the yields. It was found that the ether-aqueous sodium hydroxide medium with...
