A study of the permanganate oxidation of 4-methylpyrimidine to pyrimidine-4-carboxylic acid

Creator:

Ni, Rain Wo

Abstract:

The yields from the oxidation of 4-methylpyrimidine with potassium permanganate were found to increase from 25 to 92 percent by the addition of small amount of potassium hydroxide to the reaction mixture. Pyrimidine-4-carboxylic acid decarboxylates in hot aqueous solution to yield pyrimidine and carbon dioxide. The rate is that decarboxylation...

A study of certain reactions of 4-chloro-6-methylhydrazino-5-nitropyrimidine and the 4-methoxy and 6-dimethylamino analogs

Creator:

Tantivanich, Amnard

Abstract:

The reaction between 4- chloro- 6- methoxy- 5-nitropyrimidine and methylamine was investigated. The reaction product was identified as 4-methoxy-6-methylamino-5-nitropyrimidine from synthesis of the product via 4-chloro-6-methylamino-5-nitropyrimidine. The product was the result of displacement of chloro substituent with methylamine. The reaction occured under mild condition (e. g. 15-20 C. in dioxane)....

The synthesis and cyclization of 2,4-diaminobutyric acid

Creator:

Li, Chun-wing

Abstract:

The objectives of this study were to isolate 2, 4-diaminobutyric acid and to attempt cyclizing the acid and its disulfonamide derivative. The original synthetic method by Adamson was followed but a modified isolation procedure for the acid was employed. Following the synthesis, the acidic solution was passed through Dowex-3 ion-exchange...

Masters Thesis
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...

Masters Thesis
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...

Study of the synthesis of trans-cyclo-pentane-1,2-dicarboxylic acid

Creator:

Pozo Cisternas, Jaime

Abstract:

The object of this study is the synthesis of trans-cyclopentane-1, 2-dicarboxylic acid. Five procedures designed for the synthesis of this trans diacid are described in the literature. The procedure devised by Perkin in 1887, Fuson and Cole in 1938, and by Brenner in 1961 were investigated to determine which of...

A study of the limitations of ultraviolet spectral data for the determination of dissociation constants of organic nitrogeneous bases

Creator:

Vachananda, Sookapracha

Abstract:

Ultraviolet spectroscopic methods for the determination of dissociation constants can only be applied to those compounds having protonatable sites conjugated with or inherent in a chromophoric group of the compound. The determination of the dissociation constants of organic nitrogeneous bases by ultraviolet spectroscopic methods was found to be only reliable...

The chemistry of certain tetrahydropyrimidines

Creator:

Anderson, Donna Lee

Abstract:

Since many 1, 4, 5, 6-tetrahydropyrimidines have become available and commercially useful in recent years, a study of the chemistry of certain of these compounds has been undertaken. 2-Hydroxy- and 2-mercapto-1, 4, 5, 6-tetrahydropyrimidine have been synthesized by the condensation of urea and thiourea, respectively, with 1, 3-propanediamine, with yields...

Masters Thesis
The chlorination of uric acid by phosphorus oxychloride in the presence of certain aliphatic and aromatic amine hydrochlorides

Creator:

Haase, William Alan

Abstract:

Since the use of N, N-diethylaniline hydrochloride in the chlorination of uric acid with phosphoryl chloride seems to promote the reaction, a study of the effect of other salts of nitrogenous bases in the chlorination of uric acid was undertaken. When N, N-diethylaniline hydrochloride was used in lieu of the...

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...

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....
