Beschreibung

Allgemeine Beschreibung

B-Methoxydiisopinocampheylborane (Ipc₂BOMe) is an organoborane compound, which is prepared from excess α-pinene, borane dimethylsulfide, and methanol via the formation of an intermediate diisocampheylborane. Ipc₂BOMe is used as a versatile reagent for the construction of C-C bonds in asymmetric synthesis.
