Descripción

General description

Allylboronic acid pinacol ester is used as a nucleophile in the catalytic allylation of simple ketoimines.

Application

Reagent used for

• Palladium-catalyzed Suzuki-Miyaura cross-coupling reactions and olefin metathesis
• Intermolecular radical additions
• Allylboration of aldehydes catalyzed by chiral spirobiindane diol (SPINOL) based phosphoric acids
• Cobalt-catalyzed regioselective hydrovinylation of dienes with alkenes
• Nucleic acid-templated energy transfer leading to a photorelease reaction
• Stereoselective indium-catalyzed Hosomi-Sakurai reactions

Reagent used in Preparation of

• Cyclic sulfone hydroxyethylamines as BACE1 inhibitors for reduction of Amyloid β-Peptides
• Transmetalation of carbene Ru iodide with Ag carboxylates to give C-H-activated Ru carbene complexes as catalysts for Z-selective olefin metathesis
• Allylboronation reagent for the preparation of allylic alcohols, and homoallylic amines.
