“…2-{(1 E )-3-[( E )-1-Phenylhept-1-en-3-yloxy]prop-1-enyl}-4,4,5,5-tetramethyl-1,3,2-dioxaborol ane (6a). A microwave-compatible reaction vessel was charged with 56 mg of Cp 2 Zr(H)Cl (0.05 equiv, 0.22 mmol) and 0.33 mL of CH 2 Cl 2 (3.0 M in alkyne). The resulting suspension was cooled to 0 °C, and 1.00 g of propargylic ether 5a (4.38 mmol) and 617 mg of pinacolborane (1.1 equiv, 4.82 mmol) were added.…”

Strategies for Expanding Structural Diversity Available from Olefin Isomerization−Claisen Rearrangement Reactions

Boron-substituted di(allyl) ethers provide an efficient conduit for expanding the structural diversity available from olefin isomerization-Claisen rearrangement (ICR) reactions. Easily prepared allyl propargyl ethers undergo chemoselective Zr(IV)-catalyzed hydroboration to afford the boron-substituted ICR substrates. The boron-substituted allyl residue undergoes chemoselective Ir(I)-catalyzed olefin isomerization and in situ Claisen rearrangement to afford stereodefined beta-boryl aldehyde products. Functionalization of the C-B linkage by oxidation or Suzuki cross-coupling provides a route to Claisen adducts previously inaccessible from the ICR methodology.
