The reaction of methylhydrazine with various 2-substituted 4,6-dimethoxy-5-nitropyrimidines

Creator:: Landberg, Björn Erik
Resource Type:: Masters Thesis

A study of the anomalous reaction of 4, 6-dimethoxy-5-nitropyrimidine with methylhydrazine

Creator:: Lehmkuhl, Frank Arvid
Resource Type:: Dissertation

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 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...

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...

A study of certain novel reactions of 4,6-dimethoxy-5-nitropyrimidine

Creator:: Harper, Richard Waltz
Abstract:: Reaction of 4, 6-dimethoxy-5-nitropyrimidine [I], with refluxing pyridine, was discovered to yield the methylpyridinium salt of 1, 6-dihydr -4-hydroxy-1-methyl-5-nitro-6-oxopyrimidine [III]. Possible use of I as a general N-methylating agent was explored. No appreciable reaction occurred between I and refluxing excess n-butyl alcohol. Similar reaction involving quinoline failed to yield an...

Hydroperoxide formation in the radiolysis of aqueous DNA and the pyrimidine bases

Creator:: Schwiebert, Maris Carol
Abstract:: The formation of cytosine hydroperoxide was detected in aqueous cytosine solutions irradiated with Co-60 γ-rays at pH 2. The nucleotide of cytosine, cytidylic acid, forms a hydroperoxide which was detected in neutral solution. The stability of the hydroperoxides of cytosine, thymine, and their nucleotides was found to be a function...

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...

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...
