The Modified Stereospecific Stille Reaction: Palladium-Catalyzed Cross-Coupling Reactions Involving Secondary and Tertiary Alkyl Carbastannatranes
… of transition metal-catalyzed cross-coupling reactions is given. While the formation of C(sp<sup>2</sup>)–C(sp<sup>2</sup>) bonds has been studied extensively, C(sp<sup>3</sup>)-C(sp<sup>2</sup>) bond formation still presents a challenge due to competitive β-hydride elimination and slow …

Advances in the Stille reaction and new methods for continuous flow Pd-catalyzed C-N bond forming reactions
… ligand, XPhos, for the palladium-catalyzed Stille reaction has been developed. This method allows for the coupling of aryl chlorides with a range of tributylarylstannanes to produce the corresponding biaryl compounds in good to excellent yields (61-98%) in short reaction times (4 h). …

Synthesis of Biologically Active Tropolones and Stereochemically Rich Compounds via Cross-Coupling Reactions
… compounds, through cross-coupling reactions, paves the way for entry into a whole new ligand class and asymmetric catalysis in contrast to the abundant benzenoid based privileged ligands.</p> <p>The Biscoe lab studies asymmetric C–C bond formation utilizing cross-coupling reactions …

Synthesis of [beta]-heteroaryl propionates via trapping of carbocations with [pi]-nucleophiles, efforts towards the total synthesis of acutumine, and the design, synthesis, and thermodynamics of protein-ligand interactions at the Src SH2 domain
… those with contiguous quaternary centers. This reaction also provided [beta]-heteroaryl propionates which were previously inaccessible by known methods by exploiting non-traditional Friedel Crafts reactivity. Good diastereoselectivity was also achieved when a chiral auxiliary was incorporated …

Synthesis of Crowded Tolanes: Models for Molecular Recognition
… intramolecular noncovalent interactions. The Stille cross-coupling reaction allowed synthesis of both arylacetylenes and tolanes from aryl iodides. The Stille reaction is usually slow for electron rich aryl iodides (such as these aryl iodides that are substituted resorcinol derivatives). …

Synthesis and reactivity of alpha-thio-beta-chloroacrylamides and alpha-thio-beta-chloroenones
… and stereoselectivity a very high priority. Reactions which can be conducted under mild reaction conditions and, ideally in an environmentally attractive manner, are particularly advantageous. The principal objective of this thesis was to explore the synthesis, reactivity and synthetic …
