Design, Synthesis, and Characterization of Glycodendrons Through Small Molecule and Linear Polymer Models
… and characterization of glycopolymer-dendron thiol-ene coupling reactions with the long-term goal of increasing biocompatibility of near infrared (NIR) fluorophores for bioimaging applications. A design of experiments was used with small molecule model compounds to determine the parameters for …

Investigations of Thioether Generation for S-D-Ribosyl-L-homocysteine Synthesis
… This work examines four methods of thioether generation following two mechanisms, bimolecular nucleophilic substitution (S<sub>N</sub>2) and radical-initiated thiol-ene coupling, in an attempt to generate SRH in a more efficient and reproducible manner. Both mechanisms address key objectives …

Synthesis and transformations of 2-thiocarbohydrates
… 2-thiocyanates were reduced to the corresponding thiols using appropriate reagents and reaction conditions. The screening of substrates, stereochemical outcome and the reaction mechanism are discussed briefly (Scheme I). Scheme I. Synthesis of the 2-thiocyanates II and reductions to 2-thiols III & …

Immobilized Bis-Indenyl Ligands for Stable and Cost-Effective Metallocene Catalysts of Hydrogenation and Polymerization Reactions
… chemicals, pharmaceuticals, and plastics. Homogeneous catalysts for the processes that have low stability and their separation is difficult. Therefore, the development of new highly active and stable catalysts for hydrogenations and polymerizations is a necessity. The objective of this research …
