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...

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...
