Improving Efficiency vis Catalytic and Multicatalytic Reactions
Oxidative addition and reductive elimination are two fundamental steps common to many different catalytic reactions. Insertion into C-X bonds is particularly prevalent as one of the first steps in a catalytic cycle. We have been exploring the synthetic potential associated with reversible oxidative addition into carbon-halogen bond and recently developed a metal catalyzed carboiodination reaction(1-2). This lecture will describe the scope and limitations of the reaction including recent work that has expanded the scope and led to the development of a metal catalyzed hydrohalogenation reaction(3). C-H functionalization remains one of the most active areas of research. We will present our recent work in this field highlighting C-H bond activation as a key step in spirocyclization reactions(4-5).

Professor Lautens' group is focused on the investigation and development of novel transition-metal-mediated organic transformations. Some projects include catalyst-controlled asymmetric transformations while others focus on controlled tandem or domino processes. Of particular interest are reactions that can efficiently construct frameworks of pharmaceutical compounds or fragments of biologically-active natural products.
