Part I: Synthetic studies toward the southern portion of Azaspiracid-1; Part II: Total synthesis of amphidinolide B₁ and the proposed structure of amphidinolide B₂

Creator:: Lu, Liang
Abstract:: The structural architecture present in marine toxin azaspiracid - 20 stereocenters, 9 rings, 3 separated spirocenters - has attracted considerable synthetic attention. Our efforts toward the synthesis of azaspiracid have led to the completion of both C₁-C₂₆ northern and C₂₇-C₄₀ southern halves. Herein, the synthesis of southern FGHI ring system...

Ring expansion reactions of alkoxides and their application toward synthesis of large ring hormone models

Creator:: Seitz, Earl Philip
Abstract:: The potassium salts of a series of 1-vinylcycloalk-3-en-l-ols were found to undergo ring expanding [1, 3]-sigmatropic shifts at 25° when dissolved in hexamethylphosphoramide (HMPA) or 1, 2-dimethoxyethane (DME) with 18-crown-6. The yields and reaction rates were compared with those of the corresponding Siloxy-Cope ring expansions. These anionic cases showed about...

Analysis of semi-volatile organic contaminants and their accumulation in remote aquatic ecosystems of the western US

Creator:: Ackerman, Luke K.
Abstract:: Many pesticides, polychlorinated biphenyls (PCBs), polybrominated diphenyl ethers (PBDEs), and polycyclic aromatic hydrocarbons are persistent, bio-accumulative, and toxic. These semi-volatile organic compounds (SOCs) can undergo atmospheric transport and deposition in cold, remote ecosystems. A better understanding of their accumulation in the fish of these ecosystems is important to better predict...

A study of the oxide/solution interface by capacitance measurements of electrolyte/oxide/semiconductor structures and potentiometric titrations of colloidal oxide suspensions

Creator:: Hindagolla, Suraj L.
Abstract:: The oxide/electrolyte solution interface has been studied experimentally by two methods, and a mathematical model for the interface has been developed. The change in interfacial potential with solution composition was determined through the capacitance of electrolyte/oxide/semiconductor (EOS) structures and the charge through potentiometric titrations of colloidal oxide suspensions. The differential...

Precursor Chemistry and Film Structure and Properties via Solution Deposition

Creator:: Huang, Yu
Abstract:: Chemistry of preparing dense film from solution deposition is explored with several cases in this thesis. Surface dense structure, conversion at melting point, and ion exchange in aqueous solution are the main topics covered here for the thin films of aluminum oxide phosphate and tin dioxide. Thin film density, optical...

Fluoroboranes : I. Preparation and properties of trifluoromethyldi-n-butylborane : II. A study of doboron tetrafluoride

Creator:: Self, James Maurice
Abstract:: A large-scale preparative method for potassium di-n-butylborate in triethylamine solvent has been developed. The reaction of potassium di-n-butylborate I with trifluoromethyl iodide has been shown to yield trifluoromethyl di-n-butylborane and other products. Reaction of this substance with boron trifluoride gave trifluoromethyl boron difluoride. Reactions of diboron tetrafluoride, boron tribromide, and...
