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 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 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....
