Disubstituted Z-allylic esters by Wittig-Schlosser reaction using methylenetriphenylphosphorane.

David M Hodgson1, Tanzeel Arif.   

Abstract

β-Lithiooxyphosphonium ylides, generated in situ from aldehydes and methylenetriphenylphosphorane, react with halomethyl esters to form disubstituted allylic esters in good yields and with high Z-selectivity.
