✦ Synopsis

Mono and Difunctionalization of Chiral Ferrocenyl Bisacetals. X-Ray Crystal Structure of Bis-1,1'-[(2S,4S)-(hydroxymethyl)-2-dioxane1,3]ferrocene. -The title chiral bisacetals (III) and (V) react with tBuLi and MeLi to the o-Li compounds, which are converted with electrophiles like (VI) to o-substituted derivatives such as (VII) and (VIII) in high regioselectivities but only 19-35% diastereoselectivities.
