Reduction of Esters via Aldehydes to Alcohols
Reduction of Esters to Alcohols via Aldehydes: Unsaturated Esters
Reduction of α, β-unsaturated esters to allylic alcohols
The reduction of α, β-unsaturated esters to allylic alcohols is the only reduction of carboxylic esters that is carried out exclusively with DIBAL in polar solvents, because the reduction with LiAlH4 is sometimes accompanied by a reduction of the C=C double bond to a C-C single bond
