Synthesis and use of bench-stable precatalysts with heck-type activation and progress towards the continuous-flow synthesis of atorvastatin
… a new class of bench-stable N-heterocyclic carbene nickel precatalysts for homogeneous nickel-catalysis. The nickel(II) complexes are readily activated to Ni⁰ in situ under mild conditions, via a proposed Heck-type mechanism. The precatalysts are able to facilitate carbonyl-ene, …

Nucleophilic Carbon-Carbon Bond-Forming Reactions of 2-Methylenetetrahydropyrans
<p>Reactions with 2-methylenetetrahydropyrans are underutilized in the literature, especially with respect to general methods demonstrating their nucleophilic nature. This work provides three general methods toward the synthesis of 2-β-oxygenated pyranyl substrates, which are key structural …

DEVELOPMENT OF METAL-CATALYZED REACTIONS OF ALLENES WITH IMINES AND THE INVESTIGATION OF BRΘNSTED ACID CATALYZED ENE REACTIONS
… have been discovering new reactions to generate interesting synthetic targets. As these new reactions have emerged, they are constantly tweaked so that an array of substrates can be synthesized and better catalysts can be discovered. The focus of our research is to two-fold: (1) to study …
