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

A series of chiral propargylic alcohols with high enantiomeric excess was prepared by asymmetric dihydroxylation of a,b-unsaturated esters, conversion of the diols to 4-(chloromethyl)-1,3-dioxolane intermediates, and base-induced elimination.
