Studies toward the total synthesis of glycinoeclepin A
… the conversion of the methyl ketone to a vinyl triflate (177) followed by Sonogashira coupling. In addition, the conversion of diketone 128 to the vinyl halide 258 via a Shapiro strategy was achieved and model studies were carried out on the synthesis of vinylallene by coupling cuprate …

Total synthesis and study of myrmicarin alkaloids
… include a stereospecific palladium-catalyzed N-vinylation of a pyrrole with a vinyl triflate, a copper-catalyzed enantioselective conjugate reduction of a P-pyrrolyl enoate, and a regioselective Friedel-Crafts reaction. The synthesis of optically active and isomerically pure samples of …

Development of new transition metal-catalyzed carbon-fluorine, carbon-nitrogen, and carbon-carbon bond forming processes
… 1. Palladium-Catalyzed Fluorination of Cyclic Vinyl Triflates: Dramatic Effect of TESCF₃ as an Additive A method for the synthesis of cyclic vinyl fluorides with high levels of regiochemical fidelity has been achieved by Pd-catalysis employing a new biarylphosphine ligand and TESCF₃ as a …

Inhibitor studies on para-aminobenzoic acid synthase.
… The organic synthesis of an inhibitor containing vinyl fluoride functionality has been the focus of previous studies. The biosynthesis of 6-fluorochorismate led to the discovery that this species was an irreversible inhibitor of the P ABA synthase system. Synthesis of a vinyl fluoride was achieved …

Synthesis of α, β-Substituted Alkenylphosphonates from α-Phosphonovinyl Triflates: I) Palladium Catalyzed Suzuki-Miyaura Cross-coupling with Aryl Boronic Acids II) Palladium Catalyzed Reduction
<p>Alkenylphosphonates (vinylphosphonates) are important targets for R & D because they have interesting chemical, biological and pharmacological properties. Vinylphosphonates are used in synthesis, polymer applications, and have demonstrated potential as anticancer and antimicrobial agents.</p> …
