Treatment of esters with diisobutylaluminum hydride (DIBAL) in the presence of lithio-trialkylphosphonoacetate results in improved yields of the homologated a,B-unsaturated esters. The problematic overreduction, which has previously observed in the half reduction of esters using DIBAL, is minimal (~

Reaction of ketene silyl acetals with allylic carbonates in the presence of palladium-phosphine catalyst in dioxane gives a-ally1 esters in high yields. When the reaction is carried out with phosphine-free palladium catalyst in nitriles,cl,fi-unsaturated esters are obtained in good yields. We have
