Description

Description générale

Diisobutylaluminum hydride is commonly used as a reducing agent in organic synthesis.

Application

Diisobutylaluminum hydride can be used in the following protocols:

• As a promotor of Tishchenko reaction of aldehydes.
• Conversion of benzylidene acetals of 1,2-and 1,3-glycols to the corresponding monobenzyl ethers of the glycols.
• To generate a novel chiral reducing agent based on (S)-proline for the asymmetric reduction of prochiral ketones.
