Synthesis of pyridines and azaindoles via Diels-Alder reactions of tosyl cyanide with vinyl- and heteroarylallenes
… reactions of vinyl- and heteroarylallenes with tosyl cyanide. The synthetic elaboration of the various pyridine products via an ipso substitution strategy is also described. Part II of this thesis describes the optimization and scale-up of a reproducible synthesis of 1-iodopropyne, an important …

Synthesis of pyridines via [4 + 2] cycloadditions of vinylallenes with azadienophiles
… on [4 + 2] cycloadditions of vinylallenes with tosyl cyanide. In addition, Part III discusses the synthetic elaboration of these 2- sulfonylpyridines via nucleophilic aromatic substitution reactions. Overall, annulation strategies based on [4 + 2] cycloadditions of vinylallenes with …

Challenging the Limitations of the Streitwieser Lithium Indicator Acidity Scale with Cyclopentadiene Derivatives
… cyanation of cyclopentadiene derivatives using tosyl cyanide (TsCN) as the cyanizing reagent. Neutral cyanocyclopentadienes are thermally unstable (likely they polymerize), so we developed workup procedures that maintained these compounds in their anionic, conjugate-base forms (as potassium …
