Treatment of esters with diisobutylaluminium hydride (DIBAL) in the presence of lithio-trialkylphosphonoacetate results in improved yields of the homologated α,β-unsaturated esters.The problematic overreduction, which has previously observed in the half reduction of esters using DIBAL, is minimal (3percent) under these conditions.
