Descripción

General description

Diisobutylaluminum hydride is a reducing agent for many functional groups commonly used in organic synthesis.

Application

Diisobutylaluminum hydride solution (1 M in dichloromethane) has been used in the conversion of esters into α-fluoro-α,β-unsaturated esters in the presence of fluorocarboalkoxy-substituted dialkyl phosphonate anions via Horner-Wadsworth-Emmons reaction. It can be used in the multi-step synthesis of (S)-2-methyl tetrahydropyridine-N-oxide, a key structural moiety of bio-active compounds like himbacine and solenopsin-A.

Utilizada en la desbromación reductiva catalizada por Pd de los alquil bromuros secundarios. O-desbencilación y apertura del anillo de los furanósidos perbencilados. Cómoda generación in situ de HZrCp₂Cl a partir de ZrCp₂Cl₂ y DIBAL-H.
