설명

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)
