Approaches toward synthesis of the mycosporins

Creator:: Cammack, Janice H.
Abstract:: The mycosporins, formerly called P310's are secondary metabolites of fungi closely associated with fungal reproductive processes that require light. The structurally related iminomycosporins are found in marine plants and animals and may also have functions related to light. In this study, approaches toward the asymmetric synthesis of the mycosporins are...

Reactions and stereochemistry of thiolato and sulfenato cobalt (III) complexes

Creator:: Herting, Daniel L.
Abstract:: This thesis describes a study of the synthesis, stereochemistry, and reactivity of cobalt(III) cysteinato (CyS) and related thiolato complexes. The preparation of [Co(en)₂CyS]⁺ resulted in a product solution containing a mixture of diastereomers in the ratio 2.3:1 (Δ:A). The isomers were separated by ion exchange chromatography, and their absolute configurations...

Synthesis and oxidation of cysteine- and penicillamine- containing Fe(III) and Co(III) complexes. Analogs for the active metal sites of the cysteine and cysteamine dioxygenases

Creator:: Miller, Krys J.
Abstract:: The first part of this thesis describes a study of the characteristics of oxidation of a 1:2 iron(III):thiolate system in methanolic solution and in water. This system was investigated as a potential analog for the cysteine- and cysteamine-dioxygenase catalyzed 0₂-oxidation of cysteine and cysteamine, respectively, to the corresponding sulfinic acids....

Synthesis and oxidation of metal-thiolate compounds which mimic the active site function of thiolate dioxygenase enzymes

Creator:: Schussel, Leonard J.
Abstract:: Part I describes the synthesis of bis(fac-S)((tris)2-aminoethanethiolatoiron( III))iron(III) chloride. The compound was first discovered during an attempt to prepare a ternary complex of iron, thiolate and pi-acid ligand. The compound is a reasonably air-stable iron(III)-thiolate that contains a linear tri-iron cluster with each iron bridged to the adjacent iron by...
