The enantioselective Horner-Wadsworth-Emmons reaction of 2-fluoro-2-diethylphosphonoacetates with s-symmetric prochiral 2-substituted-1,3-dioxan-5-ones and 4-substituted-cyclohexanones was investigated by employing Sn(OSO 2 CF 3 ) 2 and N-ethylpiperidine in the presence of an external chiral ligand,
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 (~
