Development of organocatalyzed, intramolecular heteroatom Michael addition and application towards alkaloid synthesis

Creator:: Carlson, Erik
Abstract:: Effective methods for the enantiopure formation of substituted piperidine rings are significantly important due to their presence in alkaloid products. A valuable method to form these ring systems would be via an intramolecular heteroatom Michael addition from the corresponding enone or enal. Described herein is a methodolgy that has been...

Tertiary amine complexes of cobalt (II) and nickel (II) trifluoromethanesulfonates

Creator:: Jansky, Michael Thelen
Abstract:: Hydrated cobalt(II) and nickel(II) trifluoromethanesulfonates have been prepared by a previously reported procedure, and have been characterized for the first time as [ Co(H₂O)₆] (CF₃SO₃)₂H₂O and [Ni(H₂O)₆] (CF₃SO₃)₂. These formulations are based on analyses, near-infrared spectra, and on measurements of the ligand field electronic spectra and the magnetic susceptibilities. The...

Aryl acetylene substituent effects : the synthesis and application of biaryls

Creator:: Naffziger, Michael R.
Abstract:: The work described herein details the synthesis and application of biphenyls that probe the effects of hydrogen, Cl / Br, and methyl substituents on the aryl ring of the terminal acetylenic carbon. From this work, we successfully developed the rapid synthesis of phenyl acetylenes in 3-4 steps from inexpensive commercially...

Synthetic transformations of shikimic acid

Creator:: White, Edward D., III
Abstract:: Four strategies which involve synthetic elaboration of the shikimate nucleus are discussed. Methyl shikimate was differentially protected as the 3,4-0-cyclopentylidene ketal and as the 5- 0- tert- butyldiphenylsilyl ether. The methyl ester was then reduced with diisobutylaluminum hydride and the resulting allylic alcohol was oxidized to aldehyde 47 with pyridinium...

Steric effects in free-radical hydrogen atom abstraction reactions

Creator:: Totherow, William D.
Abstract:: A study of the relative rates of benzylic hydrogen abstractions from a series of meta and para substituted neopentylbenzenes by the bromine radical and trichloromethyl radical at 70°C has been carried out. Application of the Hammett equation yields p values of -0.75 for the bromine atom and -0.94 for the...
