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...

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...

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...

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...
