Lithium Diisobutylpiperidinohydroaluminate (LDBPA) as a Mild and Efficient Reducing Agent for the Conversion of Ester to Aldehyde

C. However, sodium diethyldihydroaluminate which isthe precursor for synthesis of SDPA is not commerciallyavailable. In the course of our program for developing newselective reducing agent, we found that lithium diisobutyl-dialkylaminohydroalumonates prepared from DIBAHsmoothly reduced esters to aldehydes at 0
