Total Synthesis of Aspidosperma Alkaloids Leuconoxine, Melodinine E and Mersicarpine and Synthetic Studies directed toward the Iboga Alkaloid Ibogaine: Progress directed toward the dimeric Cephalotaxus Alkaloid Cephalancetine C

Creator:: Kim, GilSoo
Abstract:: The first part of this manuscript is about the total synthesis of the aspidosperma alkaloids leuconoxine, melodinine E and mersicarpine. Our synthetic strategy used a radical translocation-conjugate addition cascade to construct the core of the natural product. Specifically, a vinyl radical was generated from the homolysis of the C–I bond...

Resonantly enhanced multiphoton ionization and zero kinetic energy photoelectron spectroscopy of Benzo[e]pyrene

Creator:: Harthcock, Colin, Zhang, Jie, and Kong, Wei
Abstract:: We report zero kinetic energy (ZEKE) photoelectron spectroscopy via resonantly enhanced multiphoton ionization (REMPI) for benzo[e]pyrene. Extensive vibronic coupling between the first electronically excited state and a nearby state allows b₂ symmetric modes to be observed which would normally be Franck-Condon (FC) disallowed. These vibronic modes are comparable in intensity...

Topotactic Reduction and Reoxidation of Hexagonal RCu0.5Ti0.5O3 (R =Y, Eu-Lu) Phases

Creator:: Jiang, Peng, Berthelot, Romian, Li, Jun, Sleight, A. W., and Subramanian, M. A.
Abstract:: Hexagonal AMO₂ and AMO₃ phases have the same basic structure, and intermediate compositions for this structure have been prepared by topotactic oxidation of AMO₂ phases such as RCuO₂, where R is a trivalent rare earth cation. We now find that such intermediate phases can also be prepared by topotactic reduction...

The rotational motion of molecules in crystalline solids

Creator:: Miller, R. E.
Abstract:: Theoretical studies and experimental results are presented for the rotational motion of molecule's in crystalline solids. The group theory is solved for molecules of any symmetry matrix isolated at a site in a crystal field of any symmetry. As the potential terrier to rotation of the molecule relative to the...

Determination of Reaction Product Cross Sections in the ¹³⁶Xe + ²⁰⁸Pb Multi-nucleon Transfer Reaction at E[subscript cm] = 450 MeV

Creator:: Barrett, J. Spencer
Abstract:: The yields of 235 projectile-like and target-like fragments from the interaction of ¹³⁶Xe with a thick target of ²⁰⁸Pb at a center-of-mass energy, E[subscript cm], of 450 MeV were measured using γ-γ-γ coincidence data from Gammasphere and off-line γ-ray spectroscopy. The results give an expansive picture of the production cross...

Broadening the scope of the modified-Julia reaction : a mild and stereoselective method for the synthesis of (Z)-configurated α,β-unsaturated lactones

Creator:: Giesbrecht, Heath Eugene
Abstract:: An intramolecular variant of the modified-Julia olefination was demonstrated by the synthesis of α,β-unsaturated lactones in a mild and (Z)-selective fashion. The lynchpin reagent (benzothiazol-2-sulfonyl) acetic acid was synthesized in a straightforward fashion in 86% overall yield from commercially available 2-mercaptobenzothiazole via conversion to ethyl (benzothiazol-2-ylthio)acetate by base mediated alkylation...

Development of Methods for Stereoselective Carbon-Carbon Bond Formation

Creator:: Wu, Zhenhua
Abstract:: Three distinct methods to achieve the stereoselective synthesis of carbon-carbon bonds were investigated, encompassing: (i) the formation of axially chiral biaryl molecules by enantioselective Suzuki cross-coupling, (ii) the synthesis of α-phenylalkylboronic esters by enantioselective chain extension, and (iii) the stereospecific synthesis of alkenes by eliminative cross-coupling of enantioenriched sp³-hybridized carbenoids....
