✦ Synopsis


A mild and practical procedure of Horner-Wadsworth-Emmons olefination promoted by lithium hydroxide and a-cyano phosphonates has been set up for the synthesis of a,b-unsaturated nitriles. The reaction conditions are tolerated by functionalized ketones and the exclusive formation of E-g-hydroxy a,b-unsaturated nitriles has been observed.

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,
