Abstract:

By using of 3-methoxycarbonyl-2-propenylidenediphenylmethylphosphorane as phosphorus reagent, 5-substituted-2,4-pentadienoic esters(ABA ester analogs) were synthesized in 76-92% yields under mild conditions. The Wittig reactions of this type of phosphorus ylid shows good stereoslectivity, a possible mechanism was suggested.
