The diastereoselectivity of the carbonyl addition of organolithium reagents to β-keto acetals was examined. Addition of MeLi to β-keto acetal derived from Pd(II)-catalyzed acetalization of phenyl vinyl ketone with (<I>R</I>,<I>R</I>)-2,4-pentanediol gave (4<I>R</I>,6<I>R</I>)-4,6-dimethyl-2-[(2<I>R</I>)-2-hydroxy-2-phenylpropyl]-1,3-dioxane in 75%de.
