  Structure and Reactivity of a Preactivated sp²–sp³ Diboron Reagent: Catalytic Regioselective Boration of α,β-Unsaturated Conjugated Compounds

  摘要：

  A novel sp(2)-sp(3) diboron reagent has been developed for the copper-catalyzed beta-boration of alpha,beta-unsaturated conjugated compounds. The reaction proceeds under mild conditions with various substrates, i.e., alpha,beta-unsaturated esters, ketones, nitriles, ynones, amides, and aldehydes, in the absence of additives such as phosphine and sodium tert-butoxide to provide beta-borylhomoenolates in good to excellent yields. The presence of an sp(3)-hybridized boron center, un-ambigously confirmed by X-ray crystallography, sufficiently activates the unsymmetrical pinacolato diisopropanolaminato diboron (PDIPA diboron, 2) to transfer the sp(2)-hybridized boron moiety chemoselectively. These observations suggest that the activation of one of the boron atoms is an essential step in the Cu-catalyzed beta-boration catalytic cycle.
