A pyrolysis of cis-1-trimethylsiloxy-1-cyclopropyl-3-cyclononene : the thermal isomerization of 2-phenyl-1-trimethylsiloxy-1-vinylcyclononane

Creator:: Choi, Young Bok
Abstract:: Part 1 The pyrolysis of cis-1-trimethylsiloxy-1-cyclopr opyl-3-cyclononene in the temperature range 285-350° is described. Instead of siloxy-Cope rearrangement, undesired desiloxylation took place. Part 2 Gas-phase pyrolytic rearrangement of 2-phenyl-1-trimethylsiloxy-1-vinylcyclononane was investigated in a static system in the temperature range 213-330°. It was discovered that three major products resulted: cis- and...

Cyclization of organolithium and -zirconium compounds ; Rearrangements of selected anionic compounds in highly disassociative solvents

Creator:: Bass, Lawrence W.
Abstract:: Intramolecular cyclization of organometallic compounds represents a promising tool for synthesis. The reaction involves exothermic consumption of intramolecular double bonds via insertion into a carbon metal sigma bond. This represents an intramolecular example of the reaction type responsible for metal catalyzed polymerization of olefins. Organolithium reagents were found to cyclize...

Identification of a product of the Friedel-Crafts cyclization of β -(3- cyclohexenyl) propionyl chloride

Creator:: McEwen, Terry Earl
Abstract:: An improved procedure for the preparation of β-(3-cyclohexenyl) propionic acid from 4-vinylcyclohexene was developed. The Friedel-Crafts cyclization of β-(3-(3-cyclohexenyl) propionyl chloride with aluminum chloride was shown to give one bicyclic chlorine containing ketone in 41% yield. This ketone was identified by a combination of spectral and chemical methods as a...

Part I: Synthetic Studies toward C10-functionalized Lycopodium Alkaloids. Part II: Exploration of the Pummerer Cyclization and Its Application to the Total Syntheses of the Abietane Diterpenoids

Creator:: Li, Xin
Abstract:: This dissertation is separated into two parts according to the two major distinct research projects. In Part I, the full account of synthetic studies toward C10-functionalized lycopodium alkaloids is described. In Part II, the detailed discussion on the exploration of the Pummerer cyclization methodology and its application to the total...

Studies toward the synthesis of halichlorine and pinnaic acid

Creator:: Korf, Eric A.
Abstract:: Three approaches toward the core of halichlorine and pinnaic acid are described. The first approach entails a racemic transannular nitrone-olefin [3+2] cycloaddition from nitrone 238. Construction of the nitrone 238 began with aldehyde 241. Another key feature in this route involved a ring-closing metathesis for the formation of a 14-membered...

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...

The synthesis and chemistry of strained bicyclic systems

Creator:: Scerbo, Louis
Abstract:: A facile route to bicyclo(2.1.1)hexanes was developed involving the intramolecular photocyclization of 1, 5-hexadien-3-one to bicyclo(2.1.1)hexan-2-one. A study of the chemistry of bicyclo-(2.1.1)hexan-2-one was undertaken. Deuterium exchange and borohydride reduction demonstrated the strain present in the ketone. Further evidence was obtained from the failure to introduce substituents alpha to the...

The synthesis of nonactic acid

Creator:: Arco, Manuel Jose
Abstract:: Alkylation of propylene oxide with 2-lithiofuran gave alcohol I, which was smoothly converted to acetylfuran II. hydrogenation of II over rhodium on charcoal followed by Jones' oxidation afforded ketone III. Further transformation into IV was accomplished via a Wittig reaction followed by saponification with methanolic sodium hydroxide. Hydroboration of the...
