The utility of sulfur (IV) and selenium (IV) imido compounds in organic synthesis.
(Massachusetts Institute of Technology, 1977)
Approaches for the total synthesis of miroestrol.
(Massachusetts Institute of Technology, 1976)
The heat capacities of potassium dihydrogen arsenate and ammonium dihydrogen phosphate from 15 to 300⁰K. the anomalies at the curie points
(Massachusetts Institute of Technology, 1941)
Molybdenum and tungsten alkylidene complexes for cis- and trans-selective ring-opening metathesis polymerization
(Massachusetts Institute of Technology, 2015)
Chapter 1 describes the synthesis of tert-butylimido alkylidene complexes for molybdenum and tungsten. A dimer species [chemical formula] served as a bisimido precursor. After alkylation with Grignard reagent, alkylidene ...
Kinetics and dynamics controlling proton-coupled electron transfer in ribonucleotide reductase
(Massachusetts Institute of Technology, 2015)
Proton-coupled electron transfer (PCET) reactions comprise a fundamental mechanism for energy transduction in nature. In catalyzing the conversion of ribonucleotides to deoxyribonucleotides, ribonucleotide reductase (RNR) ...
Synthesis of pyridines via [4 + 2] cycloadditions of vinylallenes with azadienophiles
(Massachusetts Institute of Technology, 2015)
Pyridines are an important class of heterocycle with widespread applications. However, the efficient preparation of substituted pyridines remains a challenge in organic synthesis. This thesis describes new annulation ...
Priming and processing glycosyltransferases in bacterial N-linked glycosylation pathways
(Massachusetts Institute of Technology, 2015)
Bacterial cell surfaces prominently feature a variety of complex glycoconjugates. Although these structures are very diverse, the biosynthesis of these glycoconjugates shares common themes. In particular, a priming ...
Optical transient grating measurements of micro/nanoscale thermal transport and mechanical properties
(Massachusetts Institute of Technology, 2015)
The laser-based transient grating technique was used to study phonon mediated thermal transport in bulk and nanostructured semiconductors and surface wave propagation in a monolayer of micron sized spheres. In the transient ...
Dynamic nuclear polarization of amorphous and crystalline small molecules
(Massachusetts Institute of Technology, 2014)
Solid-state NMR has emerged to become an important technique in the studies of pharmaceutical formulations consisting of active pharmaceutical ingredients (API) and excipients. Dynamic nuclear polarization (DNP), which ...
Conformational dynamics control catalysis in disparate systems : structural insights from DNA repair and antibiotic biosynthetic enzymes
(Massachusetts Institute of Technology, 2014)
Chemical reactions allow biological systems to function. The majority of these biochemical reactions occur due to the work of protein catalysts known as enzymes. These biocatalysts are often thought of as pre-formed, static ...
