Regulation of the Biosynthesis of Thiamine by Yeast
(Kalamazoo College, 1963-05-01)Repression of the enzymes involved in the biosynthesis of thiamine and the phosphate ester of 2 methyl-4-amino-5-hydroxymethylpyrimidine was found to the folowing approximate degree: (1) a two-fold repression at 1.5 mg. ... -
The Electron Spin Resonance Spectra of Phenanthrenequinonedioxlme Copper (II)
(Kalamazoo College, 1964)The purpose of this paper and the work behind it was the investigation of the electron spin resonance spectra of a suitable copper complex. The tiny magnetic field of the spinning electron provides us with a tool for ... -
Synthesis of Gold Dibromoiodide
(Kalamazoo College, 1964)This paper will describe attempts to synthesize gold dibromoiodide, and will present evidence to show that one of the products is indeed this compound. -
Toluhydroquinone in the Von Pechmann Reaction
(Kalamazoo College, 1964-02-05) -
The Synthesis of Some Compounds Related to 3’, 4’-dihydroxy-2-dimethylaminoacetophenone to Be Tested for Anti-leukemic Activity
(Kalamazoo College, 1964-05)In this paper some of the facts known about this disease will be presented. Much work has been done in an attempt to find a cure, or ultimately, to prevent its development. Many chemical compounds have been tested, and ... -
The Synthesis and Reactions of 6-Hydroxy-5-Formylbenz0furan
(Kalamazoo College, 1964-05-04)The present study was motivated by the possibility of obtaining a compound which could serve as a common intermediate in the synthesis of psoralenes or linear benzodifurane. 6-Hydroxy-5-formylbenzofuran (III) has proven ... -
The Nature of Mercurous Ohloride
(Kalamazoo College, 1964-05-04) -
A Study of the Aromaticity of the Coumarin System Via Molecular Orbital Calculations
(Kalamazoo College, 1964-05-04)It is the purpose of this paper to attempt to predict the amount of aromaticity in coumarin and related heterocyclic molecules. More specifically, the paper will be an attempt to relate aromatic character to such calculated ... -
The Nitration of 6-Hydroxy-4-Methylcoumarin
(Kalamazoo College, 1964-05-04) -
The Thermal Decomposition of Rhenium(III) Chloride

The Synthesis of Benzo[1,2-b-5,4-b]Ddifuran and Psoralene
(Kalamazoo College, 1965-05-03)The physiological activity of the furocoumarins has raised the question as to the corresponding activity of linear furocoumarons. Unfortunately, phenyl substituted benzofurans exhibit no such activity, but some derivatives ... -
Synthesis of 7-Hydroxycoumarins by Condensation of Resorcinols with Ethyl Propiolate
(Kalamazoo College, 1965-05-03)In summary, the ethyl propiolate condensation fills out a valuable hole in the conversion of resorcinols to umbelliferoneso. Its use in the synthesis of psoralenes serves as a good example. But it should be clear, that ... -
Survey of .2,6-Dioxo-3-phthaliminopiperidine
(Kalamazoo College, 1965-05-03)2,6 - Dioxo - 3 - pthaliminopiperidine (Thalidomide) was one of the best somnolent drugs ever produced. It proved to be .virtually non-narcotic, and with extended use, produced only mild toxic effects. Unfortunately, women ... -
The Synthesis of 8-Methoxypsoralene
(Kalamazoo College, 1965-05-03) -
Certain Reactions of 4.5',8-Trimethylpsoralene and Psoralene
(Kalamazoo College, 1965-05-03)While there has been much attention devoted to the synthesis of these furanocoumarins, the chemistry of these compounds has received very little attention. This study was undertaken to elucidate some of the chemistry of ... -
The Synthesis of 4,5’, 8-Trimethylpsoralene
(Kalamazoo College, 1965-09-13) -
The Solubility Product Constant and Equivalent Conductance of Cadmium Cyanide.
(Kalamazoo College, 1966)Cadmium cyanide, along with the other halides, cyanides, and thiocyanetes of mercury, zinc, and cadmium, is taken to be a weak electrolyte. The presence of nonionized cadmium cyanide in the aqueous phase prevents the ... -
A Comparative Cost Analysis of the Use of Hops and Hop Extracts in the Brewing Industry
(Kalamazoo College, 1966)The object of this paper is to provide a brief background of the brewing industry and the problems it faces. It will then discuss the role of hops in the brewing process and the economics involved in their use. Through ... -
L.C.A.O. M.O. S.C.F. and Configuration Interaction Calculation
(Kalamazoo College, 1966-05)One of the most important fields of chemistry is the determination of the electronic structure of molecules. Since the introduction of wave mechanics by SchrUdinger and lieisenberg in the 1920's, many chemists (and ...
