Mechanistic studies on Re(V) mediated C-O bond transformations

Creator:: Zhuravlev, Fedor
Abstract:: In situ, reduction of Cp*ReO₃ by PPh₃ to form (Cp*ReO)₂(μ-O)₂ allows catalytic deoxygenation of epoxides, however, conproportionation between Reⱽ and Reⱽᴵᴵ species to form clusters of ((Cp*Re)₃(μ-O)₆}²⁺(ReO₄⁻)2 and new compound {(Cp*Re)₃(μ²-O)₃(μ³-O⁾³ReO₃}⁺(ReO₄⁻) leads to removal of rhenium from the catalytic cycle and loss of activity, The epoxide deoxygenation mediated by (Cp*ReO)₂(μ-O)₂...

C–H···O Non-Classical Hydrogen Bonding in the Stereomechanics of Organic Transformations: Theory and Recognition

Creator:: Johnston, Ryne C. and Cheong, Paul Ha-Yeon
Abstract:: This manuscript describes the role of non-classical hydrogen bonds (NCHBs), specifically C–H···O interactions, in modern synthetic organic transformations. Our goal is to point out the seminal examples where C–H···O interactions have been invoked as a key stereocontrolling element and to provide predictive value in recognizing future and/or potential C–H···O interactions...

Towards the Routine Computational Investigation of Complex Organocatalysis and Reaction Processes

Creator:: Ogba, O. Maduka
Abstract:: In this Dissertation, the mechanism and stereomechanics of complex organocatalysis and reaction processes are disclosed. The technologies and protocols currently being developed and utilized to efficiently investigate these systems using theory are highlighted. A detailed computational study of peptide-catalyzed acylations is disclosed. In particular, the magnitude of all possible non-bonding...

A Diels-Alder approach to biaryl synthesis

Creator:: Ashburn, Bradley O.
Abstract:: An expedient approach to the synthesis of a wide range of highly programmable biaryl templates has been accomplished. Utilizing the Diels-Alder [4+2] cycloaddition, a wide range of tri- and tetra-ortho-substituted biaryls have been synthesized in only three to four steps from commercially available materials. We have successfully synthesized entire classes...

High resolution spectroscopic studies of ³²S¹⁶O₃ and ³⁴S¹⁶O₃

Creator:: Barber, Jeffrey
Abstract:: The two sulfur isotopomers of sulfur trioxide, ³²S¹⁶O₃ and ³⁴S¹⁶O₃, have been studied via high resolution infrared and Coherent anti-Stokes Raman (CARS) spectroscopy. The v₁ symmetric SO stretching Q-branches observed by the latter are quite different, being especially complex for ³²S¹⁶O₃ Understanding this band structure required analysis of infrared-active hot...

Catalyst selective and regiodivergent O- to C- or N-carboxyl transfer of pyrazolyl carbonates: synthetic and computational studies

Creator:: Gould, Eoin, Walden, Daniel M., Kasten, Kevin, Johnston, Ryne C., Wu, Jiufeng, Slawin, Alexandra M., Mustard, Thomas J. L., Johnston, Brittany, Davies, Tony, Cheong, Paul Ha-Yeon, and Smith, Andrew D.
Abstract:: The regiodivergent O- to C- or N-carboxyl transfer of pyrazolyl carbonates is described, with DMAP giving preferential N-carboxylation and triazolinylidenes promoting selective C-carboxylation (both with up to >99 : 1 regioselectivity). An enantioselective O- to C-carboxyl variant using NHC catalysis is demonstrated (up to 92% ee), while mechanistic and DFT studies outline...
