Thesis advisor: James P. Morken / Detailed within this dissertation are three new reactions involving allylboron reagents. Chapter 1 describes the development of Pd-catalyzed allyl-allyl cross-coupling for the preparation of enantioenriched all-carbon quaternary stereogenic centers. This methodology represents a novel approach to a significant challenge for synthetic chemists. Subsequently, an allyl-allyl cross-coupling is described which generates functionally differentiated 1,5-dienes. Such structures allow for several chemoselective manipulations, which add a significant practical note to this cross-coupling methodology. Chapter 2 details the development of the allylboration of nitrosobenzene with (Z)-crotylboronate derivatives, which results in the formation of branched allylic alcohols. This methodology provides a regioselective complement to standard boron oxidation conditions. / Thesis (PhD) — Boston College, 2012. / Submitted to: Boston College.
