애플리케이션

Employed in a "double" Heck-Mizoroki arylation leading to β,β-diarylated vinyl boronates which react with an additional aryl halide to form Π-extended systems. This approach was used to prepare conjugated dendrimers. Also used to prepare γ-carbonyl vinyl boronates via a light-induced radical addition of xanthates.
Reagent used for
  • Suzuki-Miyaura coupling reactions
  • Mizoroki-Heck reactions (cascade reaction)
  • Intramolecular Nozaki-Hiyama-Kishi reactions
  • Stereoselective Cu-catalyzed γ-selective and stereospecific coupling
  • Control of stereoselectivity and mechanistic portrait on intramolecular (4+1)-cycloaddition of dialkoxycarbenes
  • Regio- and stereoselective synthesis of trisubstituted alkenes via gold(I)-catalyzed hydrophosphoryloxylation of haloalkynes followed by Pd-catalyzed consecutive cross-coupling reactions
  • Asymmetric Birch reductive alkylation

Reagent used in Preparation of
  • Molecular tubes for lipid sensing
  • Enzymatic inhibitors, antibiotics, receptor analogs, and other biologically significant compounds (including total syntheses)

A new stereoselective synthesis of trisubstituted alkenes is developed. Hydrophosphoryloxylation of haloalkynes provides Z-alkenyl halophosphates, which undergo Pd-catalyzed consecutive cross-coupling reactions to afford regio- and stereodefined trisubstituted alkenes.

A total synthesis of LL-Z1640-2 (2), a potent and selective kinase inhibitor, has been completed. The key step of the convergent synthesis utilized a late-stage intramolecular Nozaki-Hiyama-Kishi (NHK) reaction to close the macrocycle at the C6'-C7' bond.

The stereoselective synthesis of 5-5, 6-5, and 7-5 fused O-heterocyclic compounds is reported. The key reaction is a formal intramolecular (4 + 1)-cycloaddition involving a dialkoxycarbene and an electron-deficient diene where the stereoselectivity is dependent on the length of the

Gamma-carbonyl vinyl boronates can be prepared by a visible light induced radical chain addition of an S-acyl dithiocarbonate (xanthate) to the pinacol ester of vinyl boronic acid, followed by treatment with base.

A Cu-catalyzed γ-selective coupling reaction between propargylic phosphates and aryl- or alkenylboronates afforded aryl- or alkenyl-conjugated allenes. The reaction showed excellent functional group compatibility in both the propargylic substrates and the boronates. The reaction of an enantioenriched propargylic phosphate proceeded
